Cisco WAN :: 1921 / 1941 - Unable To See HWIC-1DSU-56K4?
Aug 4, 2011
We are currently moving from 1841 (EOL) to 1921/1941 routers. According to the module support doc [URL] this HWIC-1DSU-56K4 card is supported. We have tried both the 1921 and 1941 with the cards without any luck.

I have a 3825 router running 12.4t IOS. I installed DSU/CSU part number HWIC-1DSU-T1 in the router and it does not recognize it. Is this the right card for this router? Is there anything I can look at to determine the issue? I think the router only has 32M RAM. Below is a show hardware. Card is still currently installed.

I have an interesting problem. I've configured a site to site VPN connection between these two devices. I am using the CDMA card as the primary and only outside connection on the 1921. What happens is that by default the cellular connection is offline. When traffic is generated internally from that network to the concentrator side of this scenario the cellular connection goes online and builds the tunnel, no problem. However, I cannot initiate the tunnel from the concentrator side. I think what i need is a way to force the cellular connection to always be on, and if it fails to come back online.

The setup is a S2S VPN with failover to 3G HWIC in a Cisco 1941 however the IPSEC tunnel needs to remain up through 3G if ADSL fails.The failover works ok, however when plugging ADSL back in, the - "sh crypto session" shows both dialer 0, and dialer 1 with the crypto map session to the other side of the VPN and either side is now not pingable.The NoIP DDNS updater client runs on a server in the network and all IP resolution to host1,host2 works ok (other side of VPN is Cisco 1921 with ADSL HWIC and 3G HWIC).

We have been facing a problem at my company ! We have a Cisco Router 1921 with one HWIC-4ESW in trunking with a RuggedCom switch RSG2100.When I use the GigabitEthernet port to make a trunk, I create 2 sub-interfaces (one for each Vlan) and configure the Port on Switch as Trunk, the inter-VLan routing works with no problem.But now I need to use this configuration using the HWIC-4ESW on Router, and I can't do this work. I try creat interface Vlan for each vlan, and try creating the VLans at Router Vlans database, but no way. At router I enter in interface and try to do the switchport trunk command to add a Vlan, but doesn't work.

Does Cisco 1921-SEC/K9 support HWIC-4ESW ? I require 4 x 10/100 Ethernet ports
If yes how many ? are there any drawbacks if i use this module instead of a switch?

we bought the Cisco 1921 ISR with the HWIC-1GE-SFP to get a router that would be able to connect via fiber to our switches. I called Cisco and their reps recommended this router/HWIC pair to me.
I have got the basic configuration out of the way and I have discovered my router with CCP, now I would like to know how I can configure this HWIC. I have the SFP(GLC-SX-MM= ) installed correctly and it is connected to our test switch via an LC/LC cable, but when I do 'show ip interface" all ports are down except the one my workstation connects directly to the router with (gigabit0/1).

I've got an existing Cisco 1841 connecting to a 10Mbps Internet Leased line. With my current setup I've configured PAT for internet access for my users, and we also have some servers on site which are assigned public ip addresses, these can be accessed from the internet. Now we have procured a Cisco 1921 ISR to replace the old 1841, when I connect the 1921 with an identical configuration in place of the old router, 2 things happen.
1) The users accessing the net via the nat are able to work without any inconvenience (good)
2) My servers which have public IP addresses are unable to reach the internet and subsequently I am unable to reach them via the internet (very bad)

The Cisco 1921 router has two routed adapters. One is GE0/0 which I am using for my WAN interface. It is working properly. The 2nd interface is GE0/1 which is being used as my internal adapter. It is running NAT. When I attempt to reach the internet it fails while checking the exit interface. Here is the report.

I have VPDN running on our Cisco 1921 router running 15.2(1)T. Previously I was using Cisco 2801 router running 12.4(24)T4. I copied the config from the 2801 to the new 1921 router before replacing the router but now the VPDN isn't working.
Basically the users can connect and authenticate to the VPDN, but once they get the IP 192.168.12.10-20 IP, they can't access the internal servers (i.e. 192.168.12.120).
Is there any bug in the 15.2(1)T relating to VPDN?
Here's the VPDN section of the config:

I have a strange issue that I am having an issue figuring out. I am trying to login to the 1941 router through the console port. When I enter the username and password, which I just set, it fails. I am able to login under a different login but when I try to enter the enable mode the enable password doesn't work, which I just set as well. I can login with the TACACS+ login from a SSH session. Here is the line config:
line con 0

Today I got a pack of 7 Cisco T1 DSU/CSU WAN Interface Card (WIC-1DSU-T1-V2). I installed 6 of them (4 on a 2811 router and 2 on an 1841 router) and none of them would light up, show up in show controllers, or show up in show ip interface brief. Is there something I have to do aside from just inserting them in like getting software or entering in certain commands? (I installed the cards while the routers were powered off).

I 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]

Was wanting to know if these cards are compatable with the new 3945 ISRs or if their is a unique command that has to be run to recognize these. why I'm using these large routers with a T-1. Its too long of a story.

We want to puchase new Cisco ISR 1921/K9 . i want to know does it support the following sample IP-SLA commands
ip sla 2icmp-echo 172.16.1.2timeout 500frequency 1ip sla schedule 2 life forever start-time now
track 10 rtr 1 reachability
delay down 1 up 1
!
track 20 rtr 2 reachability
delay down 1 up 1
ip route 0.0.0.0 0.0.0.0 192.168.1.2 track 10ip route 0.0.0.0 0.0.0.0 172.16.1.2 track 20
Im asking above question because we will need to enable ip-sla on the mentioned router. as i read on the cisco webside, it says Cisco-ISR-1921/K9-IP Base support only IP-SLA RESPONDER feature nothing else. If Cisco-921/K9 does not support the above commands , should i go for ordering Cisco-1921-SEC/K9 ?

I just bought two 1760's off eBay to create a home lab. I would like to connect them together but am not sure how. Instead of Wic T1 cards that connect with a serial cable, they are using a WIC-1DSU-T1 cards that have ethernet ports.
I haven't been able to find out much about these except that they connect with something called a T Crossover cable. I assume this is just an ethernet cable with the pins connected in a certain way but am not sure. Are these the same as a standard cross over ethernet cable or something else?

I recently installed a WIC 1DSU-T1-V2 card into a 1841 router to add to a multilink bundle. I inserted it in Slot 1 and powered up the router and there was a new serial interface showing in the config automatically as s0/1/0. I was able to get it setup with ppp multilink and added to the multilink group. The problem is I need to do a sh controller or sh service-module to see if there are errors happening (I'm using this card as a replacement for an interface that was giving errors with this line before). I can do a sh s0/1/0 and that works but I can't see deeper. I found it odd that the serial port just appeared in the config when I booted without having to do anything, if this is correct behavior and how I see the Controller or CSU info for troubleshooting?

My 2691 Router has already 2 serial cards WIC-1DSU-T1 installed, When i install the 3rd serial card and reboot the router, it detects the 3rd card installed but 3rd card has no light.
When i do sh ver it shows 3 cards installed.
When i install this 3rd serial card to other Router then light shows on card and it works fine
So i am thinking if 2691 Router only supports 2 serial cards?

I am trying to set up a site to site ipsec connection. AT site A, I have Vlan's 652-10.55.216.0/24, Vlan653 -10.55.217.0/24, Vlan 654-10.55.217.0/24 and Vlan655-10.55.219.0/24 and at site B, Vlan650-10.55.214.0/24 and Vlan651-10.55.215.0/24.The problem is that I am unable to get any associations when i do a "sh crypto isakmp sa"/"sh crypto ipsec sa" on either router at each site.I am also unable to ping by pluging in a laptop into the site at each site. Laptop at site A is set to access vlan 655 and laptop at site B is set to acess vlan 651. I can ping all the devices from one end to the other.I have turned on debug crypto isakmp, debug crypto ipsec, debug crypto ipsec errors but dont get anything at all as output.I have attached the sh run for each router Cisco (1941/K9) and switch (Catalyst 3750) at each site.

What is the difference between HWIC-1ADSL-M and HWIC-1ADSL without the "-M"?Can either of the above ADSL cards be used in Cisco 3845 router? We are using HWIC-1ADSL-M in our Cisco 3845 routers everywhere?

I have an existing C2821 router (2 onboard GE + 1 HWIC-2FE) currently. Like to add another 1 HWIC-2FE. Saw this doc on Cisco website which states Max of 2 HWIC-2FE for Cisco2821. Want to confirm this is indeed so as another link states max of 1 HWIC-2FE.

I want a low cost solution router with 16 10/100 routed ports...The idea is to club 16 different segments on ofc to this router via media convertor and there will be dynamic protocols such as EIGRP or higher running between these segments.
The router needs to be security enabled...the equipments needs to be a router by defination (not a layer 3 switch)..As per my understanding there is limitation on number of HWIC-2 FE that can be put in ISR G2 series due to which I cannot reach that figure...
Kindly let me know if i can use SM-ES3-16-P in the place of HWIC-2FE for this kind of requirement.
