Cisco Switching/Routing :: Connecting A Router 182 As An Endpoint
Apr 30, 2012
I try to connect a Router as an Endpoint (Because I just want to use a SERVICE from it).Well, the issue is this: I have a SW L3 that have too much VLANS, It is routing traffic and it provides internet connection. VLAN 182 has been created at this point and in this SW L3 has configured an interface vlan 182 with an IP 10.0.82.1/28.
To this Switch L3 is connected another switch L2 with an interface vlan 182 with an IP 10.0.82.2/28. Finally I have the last switch with the same features of configuration just that this has an IP 10.0.82.3/28. In this last switch is connected the router in the Gi1/0/24 as Switch port access, this port belongs to VLAN 182. At the router, the port is gi0/0 and it has an IP 10.0.82.4/28 and is UP.
The Switch where the router is connected is reachable from this router but not by the other switches. Router can reach all the network but not in the reverse way.Router has configured an ip default gateway 10.0.82.1.
I have a Cisco 2811 Router with a NM-16ESW card installed. I've connected this to my DSL connecting and I'm trying to build myself a learning lab. From the router I can ping to the internet and back to a test computer I have connected to one of the card's ethernet ports. From the test computer, I can ping the router's WAN interface, but no further. [code]
I have two Catalyst 2960 Series (48 port) switches with the newest Cisco IOS installed. There is also a Cisco 2600 Series Router which I can't manage because it's ISP managed.
Now the problem is as follows. I'd like to create two VLANs, one in the IP range 192.168.0.xxx and the other in the 192.168.1.xxx. Now the router has a gateway IP address 192.168.1.1 .
Would it be possible to somehow connect these two VLANs with the router so that these 2 VLANs can't see each other but they can ofcourse both contact the router and exit on the internet?
We currently have a main network running through a static broadband connecting using a Cisco 1700 ADSL router, everything is working fine locally.
We are looking to rent some space in an office nearby so im going to order another business adsl connection with static IP for this site and i currently have a spare 1800 router.My question is can the cisco routers connect up like a VPN connection so both sites work together and will the connection remain online constantly so from the remote office we can access all our servers from the main network?
Also how does the IP addressing work on 2 sites. The main network uses 10.120.21.x and DHCP is assigned from a cisco router. Does the remote network assign from the same DHCP server or would the remote sites cisco router need to be setup to give out DHCP to local machines. If so what would be the best IP setup to use.
I am having an issue with connecting to a Cisco 7201 via the AUX port through a modem. The modem is plugged into the AUX port and I am dialing into the modem, everything seems to be working fine as I get a login prompt and my banner etc but I can't type anytihng. If I type then nothings happens... If I just type a bunch of random characters on the keyboard then when the authentication prompt times out and it goes back to the username, it will show a few of those characters.. I have tried many things, changing speeds etc, I have even tried changing modems and it is doing the exact same thing.Here is my config:
line aux 0 exec-timeout 2 0 modem Dialin transport input all stopbits 1 speed 115200 flowcontrol hardware
I have searched on here and found people having similar problems but no solutions. I have tried this one a Cisco 2821 with the same config and it works with no problem, the only difference is the phone line is different.
I have 2650XM router and 2620 Router Both routers have built in WIC T1 CSU/DSU cards
2620Router --
2620Router#sh int se0/0 Serial0/0 is down, line protocol is down Hardware is PQUICC with Fractional T1 CSU/DSU Description: DTE side MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation HDLC, loopback not set
[code]....
My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.
CiscoSwitch1(4506) has 3 VLANs(12,13,14) and Switch2(4948) has 3 different VLANs(22,23,24) and IP routing has been enabled in both switches with SVI interfaces for each vlan. intervlan routing is works fine.Now there is a requirement to connect these switches together. Vlan 12 on the Cisco switch 4506 has to be made available from vlan 22 from Switch2(4948). basically Vlan 12 is having a multicast source (225.0.0.0 & 226.0.0.0) which should be accessabile from vlan 22 of cisco switch 4948.I got 2 ideas
1) Create a trunk between these switches and configure L2 vlan(12) in cisco 4948...i know theoritically it should work but what my concern is Ip routing enabled in both switches will it create any issues? is it a gud solution to this requirement?
2) Create a separate IP network on the ports connecting to both switches and set up routes to the networks.ex- console(config)#ip route 192.168.10.10 255.255.255.0 192.168.20.1.
I was looking for a way to connect an AUX port from a 1700 router to a 6500 switch module console port, to see the output of the Switch's on the 1700 router, in case there is a network downtime, I could see what's going on in the switch, what cable should I use ? Also, is there is any kind of documentation for this type of config what have I seen is very few info.
I have two C2960 switches which have the management VLAN for other switches. These two switches are connected with each other via portchannel. Now the mgmt0 of few switches is connected to switch 1 and few other connect to switch 2.I have also connected the mgmt0 of switch 1 to an access port of switch 2 and vice versa.However in this set-up I am unable to reach switch1 via the mgmt0 IP address. However I can reach the mgmt0 Ip address of switch 2.I can also reach switch 1 and 2 via their int vlan IP.Has some one else experienced this and is their any specific reason why mgmt 0 IP address of switch 1 is not reachable.I have tried doing similar set-up on C3750, but have acheived same result i.e. I am unable to reach mgmt0 of switch 1.
I have seen a similar post here from last year about a 10/half connection, but this is different. I have a provider using a 2950 switch (they left CDP on so we can see it). And we have to be set to 10/full to make this connection (as you know 10/half connected here would be or is horrible). I have had this connection running on my 2921 router w/o issue but when I connect it to my 3560X, then I get no link light (shows down/down, not connected).
What else to know about what has been tried: Connecting link to switch with switch set to auto/auto (sp/dup). Speed is 10 (as it should be) but of course w/o the other side pulsing the voltage to know what to auto to, it defaults to half so this is unacceptabel, but, I do get a link light and can pass traffic, it's just a horrible experience.
Also tried the same setting speed and duplex vs. auto disco speed and duplex on other ports of the switch, no difference, same results. Also different patch cables, same results.
My current work around is to connect the providers 2950 (10/full) to my 2921 router @ (10/full) with a BVI to another port on the router which continues on to my 3560X at 1G/full. And this works just fine. Here's more info from my 3560X and the providers 2950:
In our LAN network design, we have two Nexus 7010 switches on the core connected via vPC. Then LAN access switches are directly connected to the Core Nexus switches via regular port channels on the 3750's and vPC on Nexus. The core Nexus switches will be linked to an existing LAN network and the applications will be progressively migrated from the old to the new network.In this scenario, three VDCs are planned to be configured on the Nexus - One for the Interconnect (and WAN at a later stage), one for the LAN/local services and one for the building facilities/local services.
We have 2 nexus 5K installed in our data centre recently and we are connecting new three servers to nexus switches. Each server has 2 10GB ports . 1 port of serverA is connected 5K1 and other port is connected 5K2 ( sameway other 2 server connected to Neuxs 5K1 and 5K2 Switches).So do we need to create each VPC with Portchannel (like VPC 1,2 and 3 ) for each server connection?
I have packet loss with QoS configured and I was wondering is it somehow connected with the QoS configured on the switch.The traffic is passing through fa0/19 and gi0/1 interfaces.
This is for a short temporary time until I get cisco 3560s in place. I have a 2921 configured and it is connecting to an HP non managed non VLAN switch and I cant get any traffic to pass from my computer to the router (pings or anything). Here is brief configuration that should be enough. [code]
Here are my vlans 1-default, 2-management, 192-data, 92-voice, i believe its running rapid spanning tree protocol. Do i have to take off encapsulation on my data vlan to get it to work or make the data vlan default vlan for everything. I am lost as to why this is not working.
I have a customer who just bought a pair of N5K and wanted to replace his current HP E3800 as Core. He wants to use the 4 x stacked HP E3800 connect back to the N5K. Will I be able to utilize VPC through a bundled 2 or 4 x 10G (40G) connection (10 or 20G on 1 switch, and 10 or 20G on another switch) from the stacked HP E3800s to the N5548s? I know you can do that with Cisco 3750s.
I have a 892 router configured on fa0 with vlan1 and a catalist 3560. On catalist all ports are in access mode and vlan1. When I'm connecting port fa0 from router to catalist, the catalist port is shuted down What should I do on router on catalist to make the connection working ?
I have a small network using a 24 port 3750 switch. I need to add five computers in another room and only have one Cat 6 cable running there and no room left on the 3750. I got a 3650 to put in the new room with the new computers. The problem is, whenever I plug the new switch into the 3750, it shuts down the port and gives me an err-disable. I can do a shut/no shut and re-enable the port. I searched the web and read about trunking and clusters. I'm not sure which, if either, is appropriate. I see various documentation that shows you can put one switch behind the other. But nothing tells me the configuration which will allow it.
we have two nexus 7k connected via vPC peer. We have edge switch connected to the core using HSRP via vPC.Now we have 1 orphan port connected to each Nexus (WLC).The problem is i cant seem to connect / ping the WLC (only 1 of them) that is connected to the orphan port and i think it is probably due to the packet arriving at the secondary HSRP and traversing through peer-link and dropping the packet.
Now what is the best practise for HSRP with vPC for orphan ports ? The problem is i can only ping 1 wlc from a machine. on doing a traceroute i find that the packets seems reach N7k1 and reach wlc that is connected to its own port but not to the WLC that is connected to N7k2 due to the packet travesing through peer-link and dropping at the peer-link.Now what is the best practise to sort this out and reach both WLC at the same time ? Do i move the WLC 2 to N7k1 ?
We have 2x WS-C3560X-48 with the 10Gb SFP C3KX-NM-10G module.I want to use the 10Gb SFP (with a redundant 1Gb link) between each of the switches.Below is the configuration what I think I should use. Is this correct?
SWITCH1 int TE1/1 switchport trunk encapsulation dot1q switchport mode trunk channel-group 1 mode active
[code]....
We also want to utilise Link Agrrigation for the servers that attach to the switch. Would this config be correct?
port-channel load-balance src-ip int range x switchport mode access switchport access vlan 1 (They are all on the default vlan) spanning-tree portfast channel-group x mode active
(Then I would configure the LACP config on the server) Is there anything I am missing?
I bought refurbished Catalyst 2950. I followed all steps(even ip address and subnetmask and ..etc) guided in [URL] no thing happen, my computer doesn't connect internet. I guess switch has no routing.. Before bought that, i thought it is plug and play type. And now having some serious issue which i have to configure via telnet and/or ssh.
I have 4900M with X2-10G-LX4I need to have a link from it to 3560X GLC-SX-MM using MM Fiber Patch Cord.any configuration required in 4900M to change the speed of X2-10GB-LX4 to 1GB ?
Scenario: Two buildings connected with a private leased fiber line, so it does operate as a LAN. There are several subnets and everyone at both buildings needs to be able to access all subnets. However the physical machines on those subnets are building specific:
The majority of the traffic between the subnets is specific to the buildings as well (i.e. most of the traffic is between 10.1 and 10.3 or 10.2 and 10.4).
Currently I have a Catalyst 3560 at Building 1 operating as the single "core" L3 router (and then a variety of switches connected to that). I have another 3560 at Building 2 that I'd like to turn in to the "master" L3 router for the two subnets primarily used by Building 2. In other words, make it so traffic from 10.1 to 10.3 doesn't have to run to building 1 just to get back to building 2.
I've got a basic knowledge of adding VLANs, VLAN interfaces and a static routes. The part that I'm getting confused on is that the Building 1 core router needs to make its default route to the firewall (and on to the internet) but "know" that traffic on vlans 10 and 30 gets sent across the fiber line to the other router. So I'm assuming this gets done with some combination of vlan definitions, vlan interfaces and static ip routes on each router.
I am have a little trouble setting up my home lab. I have a 3620 with two ethernet ports and a 3640 with four ethernet ports. I also have a 3500XL switch that I am using to connect the two together, but I can't seem to get each one to ping.
Here are my configs:
3500XL 3500XL-BottomSwitch#show run Building configuration... Current configuration: ! version 12.0
If I have two switches in a stack can both stack able switches be connected to a core switch through gbics or just only one switch can be connected to the core and the other switch connects to the other stack able switch through an Ethernet port which uses as a gateway to the core switch?
- Cisco 1841 connected to the internet on fa0/1 - LAN connected to fa0/0/1 (switch port, connected to Vlan1)
On my LAN I have a web server that houses different websites. Those websites have DNS records that point to my public IP address, located on fa0/1. From the outside I can reach the websites perfectly, but I can't reach them from the inside. So it looks like I can't seem to connect from my local LAN address to the public ip address on the Cisco (who then should NAT it to the correct server)
Here is a snippet from my config:
--NAT-- ip nat inside source static tcp 192.168.0.3 80 interface FastEthernet0/1 80 ip nat inside source route-map Internet interface FastEthernet0/1 overload
--OUTSIDE INTERFACE-- interface FastEthernet0/1 description WAN ip address dhcp ip access-group WAN-IN in [ code]...
--INSIDE INTERFACE-- interface Vlan1 description LAN ip address 192.168.0.254 255.255.255.0 ip access-group LAN-IN in [Code]....
I have a WS-X6816-10G-2T module with X2-10GB-SR modules. I will be getting a SMF hand off and the length of the termination is around 100 meters. (I will be getting another hand off for Inter-DC link for which I have X2-10GB-LR module). The question is can I connect this SMF hand off (short length) on the SR module?
When i connect two cisco 2960 series switchs via stright trough cable causes delay in transmission sw1 has vlans and having trunk port connected to router all vlans are able to access internet sw2 is connected to vlan5 on switch1 sw2 has factory default configuration computers on sw2 can access internet but I have low bandwith problem on sw2 there is transmission delay problem?
I have a 3750X four-switch stack acting as the core of a fairly simple LAN. All I need to achieve (and this seems inordinately hard, but it is entirely likely that I'm just being dense) is to get access to the internet through my core switch, through the firewall and out through my VSAT. I've spoken at some length with the firewall providers (Cyberoam) and they tell me all I need to do when I migrate onto my new system (Cyberoam is currently in place at the entrance to our existing LAN) is change the local IP address of the Firewall, plug in the new switch to the LAN port, and away I go. Tried that, didn't work, so obviously I'm missing something.
I have issue with connectivity 3750G with Dlink Switch, it cannot connect to non-cisco switch with fiber , But CISCO to CISCO switch it shows connectivity. My question is that is there any configuration on Cisco 3750G switch to connect with non-cisco switch through fiber (SFP) ?
I am planning on deploying a 2960 switch and will need to uplink it to a 4510 switch. There are 2 TenGig Ports available and I was thinking of uplinking one of them to the 1Gb SFP port on the 2960. Would this work?
I have got a new 48port Cisco catalyst 4948 switch, which I configured as a VTP client and connected to Cisco 3750 which is a VTP Server (this switch is on production network). I connected port g1/0/48 from 3750 to port g1/48 on 4948 through a straight cable and made both ports as trunk port (I also tried through cross cable). The problem is these two switches are not detecting. For testing I connected a PC directly to one of the port on 4948 (making that a switch port) still the LED on switch didn’t glow up. Is there any special command needs to be run on 4948 switches to activate its physical ports?
