Aug 7, 2011

I'm going to be swapping out a WIC-1DSU-T1-V2  for a new VWIC2-2MFT-T1/E1, going from one to two T-1s. This is on a 2800 router running 12.4(23)
configuration examples for the two T-1 setup ?
commands to verify the installation (show me the two T-1s are successfully bonded and communicating as one logical entity) ?

Cisco WAN :: VWIC2-2MFT-T1/E1 - PPP Multilink Configuration

Jun 15, 2011

I think I have my PPP multilink setup correctly.  Though I am getting AL lights on one of my connections via a VWIC2-2MFT-T1/E1 card.  One AL light is on at each location.  Though I checked with my ISP and they said it was my network cables as everything looked good on their end.  Currently one T1 circuit is connected at each end so users do not see a disruption.  This is a new install with two routers and the config is shown below.
Router 1-----
controller T1 0/0/0
cablelength long 0db
channel-group 0 timeslots 1-24

I'm just double checking here because I saw one doc that didn't mention the 2900 on the data sheet but, I ve seen the 2900 listed with on others. I don't see the 2900s listed in this with the interface.

Cisco WAN :: Does VWIC2-2MFT-T1/E1 Card Work With 2911 Router

May 5, 2011

I purchased a 2911 months ago to connect a remote site via T1 circuit.I think I might be missing some hardware to make this work on the remote end. Currently have a VWIC2-2MFT-T1/E1 card.Does this WIC actually work with this router? So no reference that this VWIC works with 2911.

Cisco WAN :: 3845 - Correct To State That VWIC2-2MFT-T1/E1 Can Support Data In Addition To Voice

May 10, 2013

I have a 3845 edge router connected to the Internet via four T1s and a HWIC-4T1/E1 card. We are adding two more T1s to the mix, and I have a VWIC2-2MFT-T1/E1 card. Here are my questions:
1. Is it correct to state that the VWIC2-2MFT-T1/E1 can support data in addition to voice?

2. I can use the HWIC and VWIC cards together to utilize the 6 T1s together?

3. Do I just add the card, configure the new slot, and add it to the same channel group?
Below is the current config regarding the existing card HWIC:
card type t1 0 0
security authentication failure rate 3 log
security passwords min-length 6
logging message-counter syslog
logging buffered 51200

Cisco WAN :: 2921 - VWIC2 Not Being Recognized?

Apr 3, 2012

I have a 2921 router, with UCK9 services on it.  I've installed a VWIC2-2MFT but the system is not seeing it.  I've been told there is a command required to enable the card, is this true?  I've always done most of my UC work on the 2800 range and never had to run an enable command, it just saw the card.

Cisco WAN :: Can't Configure VWIC-2MFT-T1 On 1841

Jan 13, 2013

I have checked and re-checked before buying and this card is evidently supported on the 1841 for 'data mode only' which is all I need.  I have 3 T1s in Multilink mode and I want to use 2 of these cards (and 3 of the 4 ports) to support it.  The problem is that even though SH INVENTORY finds the card, I can't issue the "card type" command to indicate I am using it with a T1 - I get this:
R3(config)#card type  t1 1 0
% Invalid input detected at '^' marker.
So I tried to issue the "controller T1" command and it does not recognize the slot as containing a T1 card (which makes sense since the "card" command did not work).
I found numerous references to this card being supported in Cisco docs with a minimum OS around 12.2(8) - it varies based on the chassis.  I can't find the explicit OS required for the 1841 which is a concern but I am using 12.4(13r)T. SH VERSION finds "2 Channelized T1/PRI ports" which is the MFT card.
I need to get Serial interfaces configured on these cards.

Cisco WAN :: Drop-Insert On Vwic3-2mft-t1 / E1?

Jan 30, 2013

I have a problem with configuring of my vwic3-2mft-t1/e1 card on Cisco 2821 router. I need drop some raw data timeslots from E1 frame and then insert them into frame on other port. I enter the following commands:
card type e1 0 0
 controller e1 0/0/0
tdm-group 0 timeslots 1-4
clock source line
 controller e1 0/0/1
tdm-group 2 timeslots 1-4


I find these commands in Cisco 1 and 2-port T1/E1 Multiflex Voice/WAN Interface Cards for the Cisco 1700 Series Router configuration guide for vwic2 cards.But this config is not working properly. show connect output is showing status of connection "UP", show controller e1 shows no errors on both e1 ports, but data not flows between ports.What am I doing wrong? Have vwic3 and vwic2 cards different configuration procedures or not?

Cisco WAN :: 1921 And VWIC3-2MFT-t1 Support?

Mar 7, 2013

I was just given a task to setup some T1 connections. We rarely use T1 interfaces anymore as they are typically just not enough anymore. I see the newer vwic3 interfaces are supported on various 2900 series but downloaded the vwic3 configuration guide and noticed that the 1900 series routers were not in the list? Is this correct. So are vwic3-2mft-t1 ehwic cards supported or not on 1921 routers? i can see the controller interfaces but not the ports as there must be additional configuration required. Im running 15.1(4)M4 IOS version that looks to be supporting the cards.

Cisco WAN :: Clock Slips On VWIC-2MFT In 2811

Apr 11, 2005

I have a 2811 that I'm in the process of turning-up to support a 4xT1 using VWIC-2MFT-T1's.  The question is how to "correctly" set clocking on the MFT's.
As is typical of the 2MFT's, as soon as a 2nd T-1 on a VWIC-2MFT comes up, I start taking "Slip Sec"s on the 2nd T-1.  I have tried different clock source combinations, including "clock source line primary", various "network-clock-participate" (or not) combinations, and about a dozen other stab-in-the-dark configurations.  Before I started playing with it, the slips were consistently every 9 seconds.  After playing with it, I got them to every 18 seconds.  But there shouldn't be ANY.  So the question is what SHOULD the correct timing configuration be on that platform? 
The VWIC-2MFT-T1's are in slots 1 and 3, so the controllers involved are 0/1/0, 0/1/1, 0/3/0 and 0/3/1.

Cisco WAN :: Using 2921 / 51 With RPS 2300?

Jun 30, 2011

Using a Cisco 2921 router with an RPS 2300, I came across a  table in the 2900 Hardware Installation Guide that I can hardly believe:  table 5-3 seems to tell me that in order to back up ONE 2921 with RPS  power, I will need an RPS with TWO 750 Watt or TWO 1150 Watt power  supplies. Is it really true that I need to throw at least 1500  Watts of backup power at a router that has a main power supply of approx  300 W?

Cisco WAN :: Router 2921 Enough For BGP?

Oct 13, 2011

I need a router to connect to our ISP by BGP and in a future to a second ISP. Our ISP is going to provide us about 300.000 route entries by BGP. So router 2921 would be enough??? or should i go to a higher model?We are going to have 100Mbps with this ISP and probably in 3 months we'll have to double it. Also we'll need IPv6 support.I saw router performance [URL]f and it's has 480.000 PPS and 245 Mbps but for 64 bytes lenght packages. If the packets are bigger the throughput should be best I suppose... 1500 bytes about 5,5 Gbps. In the case you consider the model is sufficient, the flash or RAM should be increased?

Cisco WAN :: 2921 / VTI Tunnel On Two Different ISP?

Mar 28, 2012

i have one interesting problem with local PBR on 2921 router. Here is the case,On HQ site there is 2921 router with two directly connected ISP, and there is Branch which is connected to only one ISP. The configuration should be to connect HQ router to Branch router with two VTI tunnels, so that each tunnel on HQ site should be terminated on different ISP, and EIGRP will be monitoring each VTI status.The problem is on HQ site, there is only one way to specify router with LOCAL PBR configuration, so router should send on ISP1 terminated tunnel traffic to ISP1, and on ISP2 interface terminated tunnel traffic to ISP2.
As I know this configuratino should work, but I could't make it work on c2900-universalk9-mz.SPA.151-4.M4.bin IOS, and on c2900-universalk9-mz.SPA.152-2.T1.bin.
 Here is simple config:
ISP1 ip is
ISP2 ip is is Branch ip address.
ip vrf BRANCH

when I configure one default static route, it starts workig, but both tunnels go with specified ISP, and also there is no vrf problem,when there is no any vrf config it also don't work. gre tunnels also dont work.
