2801 Router
3550 switch
3500 switch
2 2950 switches
2 pc hosts
Basically I have both PC's pinging 4.2.2.2 DNS, Layer 2, Layer 3 intervlan routing functioning, 2801 Nat is translating, able to ping default gateway of ISP and have configured DNS from what ISP has given under my DHCP scope, however Im still not getting, web pages opening up when i open mazzila or firefox !
I have a CISCO2921. I am not able to bring up its gi0/1 interface. It stays down down.

I know that interface is not coming up because of "no media" below. Router#sh int gi0/1 | i media Auto Duplex, Auto Speed, media type is no media
I have tried media rj-45 and media sfp which have also not worked. The other end of this link is ethernet handoff. What is it that I have to do for the link to come up? If I change the connection to gi0/2, I think that will work because I see this for gi0/2:
Router#sh int gi0/2 | i media Auto Duplex, Auto Speed, media type is RJ45
I have hardcoded 1GB ports on 3750X to 1000 and full duplex for all servers connected. THe ports are not coming up with this speed and duplex settings. If I configure them to 100, I am able to see the port is up. Whereas if i connect the same servers to 2950 switches, i can see the ports working fine with 1000 speed ..we have tried with the latest universal IOS as well

Reboot for each router not resolving the problem.Deleting ip pim sparse-mode and configuring it again on one of the ASR routers resolves the problem.

We have recently purchased Catalyst 4510R-E with two PoE line cards. When we connected Cisco Wireless APs to Cat4510 PoE ports it did not come up. These WAPs are working fine on other Cisco switch with PoE ports so there is no issue with WAP. We have received two CAT4510 and on both two slots are populated with PoE line cards and on both switches WAPs are not coming up. PC/desktops are working fine on these ports.Is there any configuration required on Cat4510 to enable PoE feature.

When doing a protocol capture, I see large frames being sent from one of the servers in the chassis.
Example:
TCP:[Continuation to #1701] [Bad CheckSum]Flags=...AP..., SrcPort=HTTP(80), DstPort=2667, PayloadLen=2831, Seq=1489611217 - 1489614048, Ack=1719592331, Win=65535
I see lengths up to 6900+ bites coming from the server.
The switch has the global MTU set to 1500
system mtu routing 1500
and I can't seem to set this at the interface level. The server is configured to send 1500 length frames. Why am I seeing these jumbos? (the server is Windows 2003)
We are trying to connect 2 nexus 5558UP (5.1.(3)N1(1)) with 10G-SFP+-LR interfaces. The interfaces are not genuine cisco's (smartoptics) but as far as we can tell, they are accepted by the hardware. If we take a look at the optical levels, we can see that the switches can see eachother (double-checked by bringing down one interface to see if optical levels really disappears) on optical level, well within limits. I found a notice about changing debounce timers but this doesn't work, setting it to 0 or 1000 doesn't make a difference. Copies of the different show int commands can be found at the end of this text.

Having a strange issue here with an 7606-s chassis equipped with two sup720's, and two regular line cards. There is only one power supply, PWR-2700-AC. I recently builded this setup and powered it on last week for the first time. It ran fine for about 20 minutes while suddenly the chassis powered down.
I've checked the back of the chassis and noticed that the power supply had it's 'input ok' and 'power fail' led lit. I toggled the power switch and waited half an hour to power it on again. This time only 1 minute of joy. My first idea was the PSU due to the power fail led so I had it swapped by the supplier for another. Unfortunately, when I powered it on today, it didn't change a thing, still unexpected power downs.
So I've checked the following documentation: [URL] and followed the suggestion to power the chassis on without any modules in the slots. So I did that and it ran for 8 minutes only. However, the fan tray did respond properly when I removed the small thermal module in the upper right by increasing the fans to full speed.
Following above documentation, it points to the chassis (there is not much left). Now the real question comes, isn't there anything else that could be the cause of this?
I just finished setting up a bundle of (2) T1's in a multilink bundle and I'm having issues with one of the T1's not wanting to join the bundle.
The router I'm using on the remote office location is a 3620 router running code c3620-i-mz.121-1c.bin
The campus router which is a 7206 is setup the same exact way with multilink 240 and like I've said, serial 0/0 is joined to the bundle just fine, so we are running off one T1 connection.
The serial interface that is not working is: serial 0/1
Here is a show-run:
interface Multilink240
ip address 172.18.xxx.xxx 255.255.255.252
ip route-cache flow
ip ospf network point-to-point

I'm trying to configure intervlan routing between a cisco 2801 router and HP/Amer switches. Using int fa0/1 and subinterfaces I was sure I had it configured correctly, but I cannot ping the default gateways when I place a host in a particular vlan. Below is what I have configured.
HP switch - port 9 connects to fa0/1 on 2801
ip default-gateway 10.1.100.1
trunk 9 Trk1 trunk
trunk 10 Trk2 trunk - to another switch
[code].....
we are bringing up new ckt and nexus 7000's interface isn't coming up once telco gave a loop. and wee following msg when I do "sh int eth1/1".
(UDLD Tx Rx loop, port: error)
what does "(UDLD Tx Rx loop, port: error)" it mean?before loop. interface was showing as "Link not Connected".
I am very new at this, but we have a 2801 router running 12.4, a 3560 that acts as the "Core" switch, and a bunch of remote 2960G's that connect via fiber to different buildings.
I am tasked to VLAN this network to reduce broadcast traffic. I started by setting up a VLAN 169 on the "3560" named the VTP domain, changed to version 2, and no password. THe Core switch and remote switch can share the VTP info, I HAD the Router seeing it too (able to ping 192.168.169.1) until I changed the "Domain" and "VTP Version"
The switches see each other fine, my problem is the Router sub interface 0/0.169 I cannot get to see the VTP domain. I imagine because I don't have a "Trunk port" set on the Router, but the option is not there. Meaning I cannot do a "switchport mode trunk" on it. The only thing I see is to make it:
TCRouter(config-subif)#encapsulation dot1Q 169 native
But, my "int fas 0/0" is used now as the main interface for our "only" network 192.168.0.0, do I need to turn this over to a subinterface and make it "Native" then the difference of the subinterfaces will advertise? Here is some of my conf:
Core SW:
TCCoreSW#sh vtp status
VTP Version : running VTP2
Configuration Revision: 8
Maximum VLANs supported locally : 1005

I have a collapsed core design with routed ports between all components. Access layer switches, data center switches, core/aggregation. All routed (no spanning-tree at all).Now...I have to add an IBM BladeCenter with a BNT layer 3 switch to my topology. However, those nasties don't seem to support routed ports.How can I have a routed port on my cisco switch and a standard access port on the BNT and still establish an adjacency with an SVI? I am running OSPF, but I am labbing this in my home lab with 2 x 3550s and EIGRP.

Does Catalyst 3550 switch support inter vlan routing ?
View 12 Replies View RelatedI have this 2801 in a critical environment. We had a brief power blip, and even though the router is on UPS, something happened. Anyway, after working with TAC, they determined the flash card had gone corrupt. Lucky for me I had a spare 2801 in my office, I grabbed that flash card and plugged it in and we're back up and going.
TAC sent me a new flash card. No matter what I do, I cannot get IOS to load on this thing! I am stuck in rommon. Here's what I've tried:
tftpdnld in rommon, times out. using another 2801 as a tftp-server. doesn't complete. using xmodem. ugh. never seems to get started. booting the router with a known good flash card, so I can get to ena, and "copy tftp flash".
have used tftpd32, Solar Winds TFTP server, What's Up Gold TFTP server, and open source tftp from sourceforge. With the tftp32, it always gets to exactly 73% download and then times out (it says, I have a feeling it's noty really a timeout). I have tried having the router and tftp server the only devices on a switch, i have tried the router plugged directly into the tftp server with a cross connect cable. No happiness. The open source tftp server reported (and I have to paraphrase, I am not near the router) "client does not support block number recount" or something like that. The client being the 2801.
The iOS file is about 45M. Someone asked me if the flash card was formatted...would that matter? would the tftp even start if it wasn't?
OK, I've gone on long enough. TAC is dispatching a new card AND 2801!

i want to boot my Router's IOS from TFTP server but when I use the command: boot system tftp c2801-adventerprisek9_ivs-mz.124-24.T7.bin 172.16.10. 200; after that I write-mem, it shows the log:
-Router#wr
-Building configuration...
-ROMMON: out of room in table, cannot set "BOOT"
And when I reload the router, it cannot boot IOS from TFTP Server, sure my TFTP work well and 2801 can ping to TFTP.
Is L3 ip routing on by default in 3550s? If so is the "ip routing" command visible in the config file? If no - I assume that one would enable L3 routing with that config command.In general terms are there any IOS devices where ip routing is enabled and one would not see the "ip routing" command in config. I.E. if that command is not visible in the config could you assume there is no L3 capablity in that device?
View 1 Replies View RelatedThe layer 2 switches are connected to layer 3 Switch via trunks, and routing between layer 2 switch ports with configured SVI's on 3550. All working fine. Now I'm trying to configure routing between 2800 and 3550, I tried connecting both Straight Throught and Crossover cables to the 2800 Fa0/0 and Fa0/1 ports as well as the switchports on 3550
No switchport commands are configured however, the lights do not go on for both straight through or crossover cables. I tried connecting 1750 routers but same result. My goal is to have all the VLANS routed to the internet with configuring NAT translation the router.
I have a 3550 l3 switch configured as follows:
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'm having some problems setting up vlans to talk to each other on a 3550-12T switch. Its quite a simple setup I have, but I need to split my network up.
Currently I have a network of 192.168.25.0 255.255.255.0 I want to create a new vlan network of 192.168.30.0 255.255.255.0 So I have configured my vlan1 (default vlan) to have an ip of 192.168.25.250 for getting to the management page
I have created a vlan2 of 192.168.30.1 255.255.255.0 ?I have a port 10 linked to one of my 3560G's?In port 9 which is on vlan2 I have my pc plugged in with a static ip of 192.168.30.50 from the router I can ping any device on 192.168.25.x.
I can not ping 192.168.30.1 (which is my vlan2) nor can i ping the PC.
I have enabled ip routing But I dont have a default route, this is becase we don't have a router on the network.
I've been working with these two Cisco devices in my home off and on for several months now but I just can't take it anymore, I'm about to throw them away and go back to Linksys router.
I have a Cisco 2600 Router with only one Ethernet card in it so I have to trunk from my 3550 Switch to that device. I'd like to have my ISP and all users plug into switch and all trunk back to the router's sub interfaces. Currently, I have started over...again, and am unable to simply get the router and switch to ping each other if I put sub-interfaces on the router. See my configs:

Port F0/24 is in VLAN 1, as are all ports but Port F0/1 which is my desktop PC. I mocked it up in Packet Tracer and it works just fine. This is just a simple setup and I'm making sure I can ping between switch and router before I move to each next step.
I cannot connect to the Cisco 2801 with console cable. what to do ?
View 1 Replies View RelatedI have a 2801 router that I am replacing with a 2911. I know the ports on the 2911 are Gigabits and the 2801 are Fe. I read where the IOS would not support backup and restore on each other . I am attaching a show ver on both routers. I need to know if backup and restore would work and or what other changes would need to get done.

View 1 Replies View RelatedI have a major problem with our core 2801 router. In summary it appears that a staff member disabled password recovery, deleted the IOS and rebooted. Net result is no Rommon and no IOS on the flash. I've read that the Conf-Reg will be reset if I remove the NVRAM but I cannot identify it on the board. If I can get to Rommon I can recover. Currently I don't have Flash reader to restore to flash.
View 2 Replies View RelatedI have a 2651 that has an adsl1-wic that I am using as my DSL router. I recently acquired a 2801 that I want to replace the 2651 with. I configured the 2801 the same way as the 2651 but on a reload I get the statement that says
Setup: New interface NVIO placed in shutdown state
When I do a show interface all of the interfaces show up except the NVIO and I don't have any connectivity to the outside world. I am using Nat since I have a /29 and using nat pool overload. What am I missing? I am running IPVOICEK9-M 12.4.25c on the 2651 and adventerprise 12.4.24.T on the 2801
I have the above firewall which is working as it should but I have came across an issue with a recent upgrade to Microsoft Exchange 2007 and Outlook 2010 Autodiscovery due to the way the port forwarding has been configured for Outlook Web Access (OWA) on the router.
The router is forwarding OWA requests to the exchange server on port 8080 and the default website in IIS on the Exchange Server under which OWA sits and unfortunately Autodiscovery has been set with an SSL port of 8080. I think the reason for this is that we have an RDP server and the router is forwarding all port 443 requests to this server. Due to this Outlook clients cannot connect to Exchange through autodiscovery and cannot therefore get FREE/BUSY and a few other things.
I have 5 public IP addresses and only use two at the moment, one on the ADSL router and one on this firewall. I have no spare interfaces on either the router or the ADSL router.
My question is, is it possible to have a secondary ip address set on the public facing interface and set different rules for this IP which would allow me to forward requests on that IP to a different server?

We're looking at implementing a new phone system which will use voice over ip. Currently we have a mixture of Cisco 3750 and Cisco 3550 switches which don't support power over ethernet. Its been suggested we could continue using the current switches and power the new phones using power adapters.
Int terms of implementing qos (we don't have any at the moment) for the voice will a Cisco 3550 be OK and will having a mixture of different models using 3550 and 3750 pose any challenges with the qos policy for the voice. I believe there are differences in that the Cisco 3550 doesn't support srr-queues but having little experience with qos I'm not sure what impact this will have if any?
I am having issues working on my QOS between 4510 and 3550 switch connecting on layer 3 through a service provider. I have class maps and policy map setup on both sides and then policy map attached to interfaces however i dont see any traffic matching in policy map on 3550 switch, i do see some traffic matching on 4510 but the speed with which its increasing has my doubts about it.
