I have existing cisco 2811 (Version 12.4(3c)). I try to add a HWIC serial card into the router but the new HWIC is not detected. There is no new interfece shows up when i do show run. This HWIC is a new card just bought it.

View 1 Replies View RelatedI am attempting to add an additional ethernet port on a Cisco 2620 router using a NM-2FE2W card, however the card is not being detected. I read that this card is compatible with this model router, but I have also notice that there is a version 2 of this card. Have I ordered the wrong card or do I possibly have a defective card? My ISO version is 12.2(26) on the router.If this card is not compatible, what is the recommended card for adding an additional ethernet port on this router?
View 2 Replies View RelatedWhile I managed to connect to each router individually, I decided it was time to connect the routers together via serial; as I don't have any serial cables and need to buy some, what serial cables I need, as well as to ask whether I have the right cards in my router(s) that will allow me to do so.
I bought 3 1841 routers, and all have a 1 port serial WAN Interface Card (WIC 1-T); one router has 2 of these, and one router has a WIC-1B-S/T .. My question is, can I connect the routers with a serial cable via WIC 1-T, or do I need a 2-T
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 have a Cisco 2811 with fa 0/0 as my bearer, and a switch module for internal clients.
I have an issue with my fa 0/0 flapping, I want to move that ip configuration to fa 0/1
as this is a branch office I am reliant on the bearer port to give me coms so changing the IP addresses is difficult.
Has any one tried this with a TCL script?

I have recently purchased 2911 routers running 15.1 to replicate a system I had implemented using 2811 routers running 12.4 a few years ago. None of my applications and servers have changed, but trying to determine why my router access-list on my serial links are not behaving the same. I don't keep up with Cisco changes.
On my original system, which is a private network that distributes a lot of udp broadcast and multicast data to remote sites over 64k serial lines, I manage some of the udp broadcast data using access-lists. When I check on my 2811-based system, "show ip access-list" shows a nice distribution of filter hits showing my expected deny/permit access-list entries working as expected allowing me to filter the particular udp broadcast ports of interest on the various serial interfaces.
On my 2911 based system, with most other elements the same, the access-list is not working correctly, and I see data getting through the access control to the other side of the serial link. Using tcp dump and other tools on the remote systems my routers attach to, it looks like the access control is basically ignored... though if I "shutdown / no shutdown" the serial link between the routers, it definitely stops and restarts the flow of data, so I know data is traveling over that interface... when I run "show ip access-list" on the 2911, I see tons of hits on one deny filter, and the last "ip permit any any" filter, but other deny udp any any eq XXX port filters are simply not registering denies.. which should be triggering since I see my server sending the data, and my client systems receiving the extra data I am supposed to be filtering on the router...
Is there potentially a new feature or command set option that I am missing to correctly filter outbound data from my serial links?

i am currently trying to configure a four port ISDN BRI interface on a Cisco 2811 router.Upon upgrading to a later version of IOS, c2800nm-advipservicesk9-mz.124-25d.bin, access to the HWIC-4B-S/T module is lost, the router no longer detects it. In fact iI can only get the router to detect the module using the original IOS version c2800nm-advipservicesk9-mz.124-20.YA3.bin.
Is there some special feature needed in the IOS code to support these modules, if so what would be a suitable version/train to upgrade to?I have tried using the Cisco Software advisor tool but it generates an error when searching on a hardware configuration containing this module type.
The reason for upgrading the code is we have a potential bug with the current version which appears to be preventing the BRI interface syncing up with the providers switch (switch type correctly defined and provider confirms isdn line has been provisioned correctly).
The debug error seen is:
GMT: ISDN BR0/0/0 SERROR: L2_Go: at bailout DLCB is NULL
L2: sapi 63 tei 127 ces 0 ev 0x650
My main question though is why the module is not being detected after a code upgrade and if there is a specific code version/train needed to support this module in a 2811?
From all of the documentation I am seeing, the 2911 does not support the NM-E3/T3 serial card.
View 16 Replies View RelatedI have recently made a WAN change from T1 to fiber and my Cisco 2600 series router no longer needs to connect over the Serial T1 card. The Serial connection also provided a few voice channels for the old phone system that are no longer needed.

View 13 Replies View RelatedI have a remote site that still utilizes a single T1 connection to me. For multiple reasons we had to scrap the old T1 and have a new one put in. The old T1 resided on a T3 as channel 25. The new T1 is a standlone point to point. I removed the old config from my 7301 and programmed my 3725. I cannot figure out what is going on but the interface stays down/down. There is no loopback turned on, either manually or by the carrier. The AL LED stays amber regardless of whether or not I have a cable patched down. The CD LED remains green when I patch a cable down. LP is not light.I am using a straight through Ethernet cable to connect my 3725 to the smart jack. If you look at the show output below you will see DCD and CTS is down. Since the remote end was working and I just had the tech move the patch cable from one smart jack to another I am assuming the problem is on my side or with the carrierI already tried changing the clock sourced between internal and line. I also swapped out the WIC card for another one. I don't usually program T1 connections. [code]

We tried a Dynamode card with a different chipset and that was also not detected. We then tried a PCIe Firewire card, and that was fine, indicating that the slot itself was OK.We then tried installing Windows 7-64, and that also failed to see either card. We updated the BIOS to the latest version, which had no effect. We then tried another PC with the same motherboard and that also showed the same problem. A USB network adaptor does work, but is not an ideal solution due to space contraints.

View 6 Replies View RelatedWe have a Cisco 1760 router . We are facing sevier packet drops in the serial interface.
When i swap the router with another router link is working working fine.
Troubleshooting steps taken
1. Swap the serial cable with another working cable : no change in state
2. Reconfigure the encapsulation commands (with PPP and HDLC) : no change in state
3. Try with a decreased MTU packet Ping : no change in state
4. Decreased the Input queue and increased the output queue size using hold-queue in command : Comparatively the packet drop is reducing but still a 10 percent drop is happening.
