Cisco WAN :: InterVLan Routing Layer 3 Switch With C3560E
Apr 13, 2013
I am tryingto add a new VLAN on my C3560E Layer 3 switch for administration purpose.My goal is to make this VLAN for administration only and to let the administrators from 172.17.1.1 connect to any host of the internal network 172.16.0.0 plus exit to the internet via the default gateway 172.16.1.245.
What happened is that:
1. The host connected to Vlan30 can correctly ping the interface it is connected to.
2, The internal network can access the internet
3. The host connected to VLAN30 cannot access the internet and cannot connect to any internal server.
Do I have to add a static route? This is a production envuironment and it is my first experiment with a layer3 switching in production, so I cannot mistake
Recently I have faced following problem in my office, We have purchased two new Dell Server Power Edge R910 with built-in 10GB FC Network card. Service tag of this two servers are given bellow. 1. 7D94C2S 2. 6D94C2S You can can Check specification of this two server from dell website{ URL}
We have two CISCO switch and model is given bellow: Brand: CISCO Model: WS-C3560E-12SD
We want to connect server to switch through FC cable and both switch have SPF module. But when we connect server to switch, link do not establish even switch and server port light become off. Then we have tested the following things: 1. Connect server to server through FC cable, it is okay. 2. Connect switch to switch through same FC cable, it is okay.
I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net. My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20,I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2),my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to,go out to the internet.
my company pay a switch 3750 X. WS-C3750X-24T-E. It uses IP services basically but I failed to configure InterVLAN routing. why interVLAN routing doesn't work on my switch?
I am trying get inter vlan routing to work on a DF 300 - 24 port switch. I have an existing company network on 192.168.111.0 and want to create a vlan on 192.168.1.1 that can talk to 192.168.111.0. I have enabled layer 3 routing on the switch via console and also provided the ip routing command. I have the following VLAN's:
VLAN1 - Default 192.168.111.0 VLAN2 - 192.168.1.0
I have enabled DNS and provided my two DNS servers 192.168.111.82 & 192.168.111.212. I have set the VLAN1 interface to 192.168.111.217 and VLAN2 interface to 192.168.1.1.
Ports FE1 - FE15 are set to access ports and assigned to VLAN1 (untagged) Ports FE16 - FE24 are set to access ports and assigned to VLAN2 (untagged)
I have set a default route for the switch to 0.0.0.0 0.0.0.0 192.168.111.254 (Draytek 2600 router). I have connected a computer (A) to VLAN1 port FE3 and a computer (B) to VLAN2 port FE16. I have set Computer A default gateway to 192.168.111.217 and its IP address to 192.168.111.94. I have set Computer B default gateway to 192.168.1.1 and IP to 192.168.1.2.
Computer A has access to Mdaemon, file server via network drives but no internet (cannot ping google) and can ping computer B and RDP onto computer B.
Computer B can ping computer A and RDP onto computer A but does not have access to the company network i.e MDaemon, file server etc. It also cannot access the internet.
From the console I can ping [URL]and all ip addresses in the company network i.e. 192.168.111.82 (DNS server). If I scan computer A wirh wireshark the internet starts working weird!
vlan 10 ports 1-10 vlan 21 ports 11-20 vlan 30 port 21-30 vlan 40 ports 31-40 default vlan should be vlan 21
I have the servers, switch and router connected to vlan 21. Vlan 21 works great I can browse the internet, but I cannot ping any other vlans. router is connected to fa0/19

I got one SF 300-48 layer 3 switch I tried to configure to use it in the office network.Unfortunately I'm unable to configure the VLAN settings.I need port one for input(VLAN2),port 7-15 for another vlan(vlan3) also need to connect with the vlan 4.port 15 is another vlan(vlan4) this is for wireless.Other ports are static.It doesn't get any connections with other vlans.I wish to know how to configure vlans in GUI mode.I tried , But I can't get the Vlan setting correctly.Also,I need to know how to communicate both vlans in GUI mode.
I created a lab and I have a few issues. One with a layer 3 switch and another with a ASA 5550.
1. Layer 3 switch: I have created multiple Vlans and I am able to route between them. I can ping the switch IP but not the default gateway to the ASA. I did a tracert of the default gateway of the ASA and once I am past the Vlan gateway it fails.
2. On the ASA 5550 I created the Vlans on sub-interfaces but still cannot get to the internet. ASA config is below the switch config.
I can understand it 's one of those very basic questions , but how do I identify a Switch is Layer 2 or Layer 3 ?Looking through # show version command and checking the IOS version to be IP BASE or LAN BASE . Is it the right way ?Cisco 2960 is a Layer 2 or a Layer 3 Switch ? I noticed that access-lists could be configured which means that it 's a Layer 3 Switch , right?
I've created a scenario using a 3750 cisco as core switch ad other 6 switch model 2900 in access level.my problem is this, the router is not a cisco router, and this router is not able to make NAT on more than one subnet.Into the core switch I've created 4 VLAN and I must to give internet access to 3 of them, 192.168.0.0/24 (vlan1), 172.16.0.0/24 (vlan2), 172.17.0.0/24 (vlan3).I've connected the switch to router via gigabit ethernet 0/1 and I've assigned to this interface ip address 192.168.10.2, the router ip address is 192.168.10.1, Switch ip default-gateway is router ip address 192.168.10.1, ip default route is 0.0.0.0 0.0.0.0 192.168.10.1 I've enabled ip routing feature and I've set no switchport feature to interface gigabit ethernet 0/1.From core switch I can ping router ip address but I can't make it from all other user, and the users not able to have internet access.
Below the switch configuration (only necessary strings)
version 12.1 no service pad service timestamps debug uptime service timestamps log uptime no service password-encryption
My understanding is that even layer 2 switches like the Cisco 3500XL can have 1 IP address for management. However, I cannot seem to figure out how to configure it to get it working in a router on a stick setup. I can manage the router through SSH, but I cannot SSH to the switch.
I have made a topology by using one 3560 switch and 2 2950 switches. I have also made 2 vlans name Clients and other Servers and vlan 1 is for anagement purposes. The left 2950 switch is for clients and the right is for servers. Clients is vlan 2 and servers is vlan3 . Now what i want is that my dhcp is should assign ips to clients in vlans 2 provided that servers are in vlan 3. I am also using a border router and i have introduced a default route on the 3560 to the border router.
Now when i assign static ips to my clients pc and server dhcp then i can ping between vlans but when i try to assign ip through dhcp then it wont work. Also the default route on the switch to the border router doesnt seem to work. I can ping only the border router when i put a default route on the border router instead of the 3560 switch.
is it possible to run a Catalyst 4500 as pure Layer 2 Switch, i.e. disabling "ip routing", but still managing the switch via Fa1, i.e. the defautl mgmtVrf vrf ?I tried the following:
! no ip routing ! interface FastEthernet1 ip vrf forwarding mgmtVrf ip address 192.168.1.1 255.255.255.0 ! ip route vrf mgmtVrf 0.0.0.0 0.0.0.0 192.168.1.254 ip default-gateway 192.168.1.254
I was not able to reach the Switch even from the same subnet. Only after enabling ip routing I could manage the Switch. I haven't found any command to set ip default-gateway for a vrf. Any workaround to keep routing disabled, but still manageable via VRF?
I'm fairly new to networking but I've learned quite a bit on my own without being educated. I'm trying to just figure things out on my gear. So for my LAN party i'm going to need an internet connection. I'm not going to rely on my venues subnet though so i want to create a new /24 subnet(250 hosts is good for a start). I want my subnet to be able to speak to the outside network too.
I'm setting up a Cisco 3750 layer 3 switch with several vlans. I thought enabling routing would route between the vlans, but no such luck.What I want is to share the internet access of vlan 100 with the other vlans/ip-nets.How can I do that?
Configuring OSPF on a catalyst 3560G Switch to connect to our building next door by way of fiber. The other two switches in the other building are running OSPF, I am trying to connect to the other building and access a server which is on a switch running OSPF. I am trying to configure the switch here to run OSPF and be able to see the neighbor, but currently can't although I've identified the networks. Maybe I'm missing something, I've followed the instructions but something is not right.
RACK 1 is the old rack and NEW RACK is the rack which is going to be procurred for some new Servers. All the Servers in the RACK 1 has a default gateway as PIX Inside IP. As of now the 3560 Switches acts as Layer 2 and does not have L3 IP routing enabled. How can I enable conenctivity between 192.168.36.0 range and 192.168.57.0 range wihtout making any change to current PIX inside IP address 192.168.57.1?Is it possible that I can enable IP routing on the 3560 Switches , create interface VLAN 36 and since already Switch 2 has it 's default gateway as 192.168.57.1 , Would the traffic from 192.168.36.0 be routed to 192.168.57.1 ? Or do I need to create static route for that ?Since L3 Routing is not enabled and since the 3560 Switches are just acting as L2 , the VLAN 2 - 192.168.57.0 range does not have any interface VLAN configured. When it is changed I would need to create interface VLAN 2 on 3560 Switches?
I just received a Catalyst 2960-C (WS-C2960C-8TC-L R) switch and I am unable to sign into its web GUI in order to configure it. I've tried both the Cisco Network Assistant and Internet Explorer and I am unable to log in either way. The documentation provided by Cisco states that the default password is simply cisco and that a username is unnecessary. Needless to say, it doesn't work. I've also Googled for other default passwords (such as cisco-cisco as the username-password), none of which worked either. I've also tried resetting the switch back to its factory default a few times.
WAN -------- ASA5505 ------<802.1q trunk>----- L3 switch -----<802.1q trunk>----- L2 switch w/ VLAN support
The following VLANs exist on the ASA and both switches: VLAN 10 (10.10.10.0/24), VLAN 11 (10.10.11.0/24), and VLAN 99 (10.10.99.0/24).
The ASA5505 performs the following functions: routing to/from the WAN, firewall, NAT, and DHCP for each VLAN. It has an interface on each VLAN (10.10.x.2) for a DHCP server.
The L3 switch provides inter-VLAN routing and layer 2 switching. The L2 switch provides layer 2 switching, with VLAN support.
What should the default gateway on the L3 switch be? Should I set the IP of the physical interface connected the L3 switch to the ASA5505.
Configured Layer 3 portchannel from 6500VSS enabled switch to two different 6500 standalone switch. Configured first ip on VSS switch, second ip on standalone switch1 and third IP on standalone switch2. My question is
1. Will the portchannel be up? 2. If port channel is up, will I able to ping the connected IP's.
We are working with a contractor to upgrade our network, and I heard from them that the 5596/5548 might not need the Layer 3 module for our inter-VLAN routhing. They have yet to give me an answer.
We do have a few static routes on our current layer-3, core switch too.
I need a L2 switch with dual AC power supply and RJ45 uplink The optin I got was WS-C3560X-48T-L + C3KX-PWR-350WAC , but the problem is with uplink . There is no RJ45 1G uplink , there is only option for SFP uplink The another option was WS-C2960G-48TC-L , but there is no dual AC power supply option a good model ( Dual AC power supply , RJ 45 uplink ports (Gig) , with 48 port 100/1000 UTP)
It has ip helper configured that points to DHCP.From 4500 switch port - port x connects to 2960 port.Port x is configured as trunk between 4500 and 2960.
2960 config vlan 10 name data
All user ports are configured under vlan 10 and as access ports.Port x is trunk port connected frpm 2960 to 4500 switch allowing vlan 1 and 10 only.This switch has no default gateway configured.
We connected user PC on 2960 switchports and they were able to get the IP from DHCP server and were able to access the network? My question is how users on 2960 switch are able to access the network without ip default-gateway configured on 2960 switch?
Do you have the ability to setup DHCP servers on this layer 3 switch? I know I can with my old 3550 switch. Want to upgrade and make sure this model supports setting up dhcp servers on it.
I have a switch layer 6500 series connected to a firewall, the port configuration between them is layer 2, in another words I do not configure an IP address in the Cisco switch port to conected it in the firewall, but when a apply a policy on firewall it lose communication with others vlans, just the vlan that is connected between the switch and firewall works, attachment the design. I think that is necessary to configure the connection between the firewall and switch as layer 3 ( a port with IP address in the switch), but I would like to know why? The switch is configured with about 10 vlan and it is a inter vlan routing, a default route is configured in the switch where the gateway is the firewall.
i need to know that how can i make vlans in Linksys SRW224G4 Layer 2 manageable switch , because i have 100 users network having lots of users using more then 1 ip to connect 4 different servers having different ip class pools, what i need is, i want to use only single ip pool with Class B Address like 172.16.6.0 for all network users which all connect to far end servers through layer 2 Linksys SRW224G4 manageable switch controlling to allow different IP pools ? like 172.16.1.0 / 172.16.55.0 / 172.16.99.0 and 192.168.1.0
Two ports in C3560E are grouped together in "active" mode.These ports are connected to a EMC server. When I type as below, the channel is in SD mode. The Server admin told me that this is normal behavior since one port is active and the other is in standby mode of which are teamed together.

I have a network topology which you can see on image. All routers are Cisco 3745 with IOS (C3745-ADVENTERPRISEK9-M), Version 12.4(12). SW1 is L3- switch Cisco Catalyst WS-C3560E-24TD with IOS (C3560E-UNIVERSALK9-M 12.2(58)SE2). [code] After that I have problem. When PC with OS Windows 7 begins to work in corporate network, it sees "coflict ip addresses" and doesn't work with network. I've used wireshark and seen, when the PC send arp request a SW1 always send arp reply (see attached file). I think problem with command "ip sla responder", but I haven't searched information about it and I want understand this is bug or normal functioning.
