We have installed a VWIC-2MFT-T1 interface card into our 1841 router and the interface doesn't show up in CP. # we only need it for data. #
ROM version 12.4(13r)T, RELEASE SOFTWARE
All indications from my research show that this version should support this card, for data only.
why I can't see this card when I show interfaces?
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.
I had to dig this stuff out of storage and cobble together a router on short notice. I installed this WIC into a 2821 and I can see it when I do a show ver.

When I do a sho run I see this:
controller T1 0/0/0 framing esf linecode b8zs!controller T1 0/0/1 framing esf linecode b8zs
How do I configure IP interfaces on it though? It doesn't seem to show up as Serial ports on a sho int. Am I doing something wrong?
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.
I am trying to use the connected WIC2-2MFT, as the servial interface on my cisco 1841.But it does not show me the option, under configuration interface

We have a bit of a problem when deploying VTP v3 in our network. When command vtp primary vlan is issued, switch typically send query to appropriate multicast address in order to find out whether there is already some other one. The problem we are experiencing is that old primary server is not discovered, because it fails to reply on those multicasts.
This debug messages (from the old primary server )may be more describing.

So far, I haven't been able to find out the reason of this behaviour. In spite of that, no other strange behavior of vtp has been observed.
I 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?

Asus RT N66U wireless router (192.168.100.2 /24)
Here's my network topology:
I have two VLANs - 10 and 20. 2 DHCP pools are configured on 2 1841's interfaces - 192.168.1.0 /25 and 192.168.1.128/26 with default router sitting on 192.168.1.1 and 192.168.1.129 respectively. No issues with obtaining IP address from any of those pools.Laptop connects to L3 3550 switch (switchport access vlan 10), which, in turn, connects to 1841 router through trunk (with VLANs 10 and 20 allowed).3550 is connected to 2960 through trunk with VLANs 10 and 20 allowed.Wireless router is connected to 2960.I can successfully ping my wireless router and outside world from 1841 from fa0/1 interface, but not from fa0/1.10 or fa0/1.20 sub-interfaces - all packets got dropped. My laptop can obtain IP from both pools (depending on port I connect it to), but can't ping my wireless router and anything beyond it.

I have a Cisco 1841 router at home with version 12.4(13r)T advanced ip services. The setup is extremely simple:
1) PPPOE dialer to my service provider over ADSL
2) Nat overload on the dialer interface.
3) 2 V LAN s one for home network (wired) and one for wireless both v LAN's are connected through interface v LAN s respectively.
My problem is when I configure static NAT to map RDP or any other protocol to inside hosts this does n`t work.
"
ip nat source static tcp 192.168.20.3 2222 interface Dialer1 2222
ip nat source static tcp 192.168.20.3 3389 xx.xx.xx.xx 3389 extendable
ip nat inside source list 20 interface Dialer1 overload
"
When I open wire shark and sniff the traffic on home computer which is the one I`m trying to reach I can't see any traffic. And While performing Nat debugging I am also not able to see traffic going to that port (for example 3389).
I've got an 1841 router and am using NAT to expose certain IPs and ports to the outside world so that external users can see internal resources (namely, web sites). However, I can't seem to get it running such that I can visit the external IP address from inside the network and get the router to turn the request around so that it is redirected back inside the network. Shouldn't this be possible? Our previous router (a non-Cisco) was able to do this, but I can't seem to get the new one to do it.
A couple of key config lines:
interface FastEthernet0/0
ip address a.b.c.178 255.255.255.240

I've never had a router's CPU suddenly hit 99% and just stay like it for hours even after a reboot. This router really does nothing with regards to CPU, I'm looking at it's CPU history (via SolarWinds Orion NPM software that we use) and it is arounf 1-3% all the time for the past 2 years.

what is the latest firmware for cisco 1841 ? is firmware and router IOS image are same ?
View 1 Replies View RelatedWe currently have a Cisco 1841 router with version 12.4(1c) of IOS using image c1841-ipbase-mz.124-1c.bin. Our goal is to make it so our router can fully support IPv6. The current IOS version cannot. I've seen a site that seems to indicate 12.4T does support with IP Base image but recently had Cisco tell me with the latest IOS release 15.1.4.M4 that I have to use either the "Advanced Enterprise Services" or "Advanced IP Services" image. Did Cisco just remove IPv6 from IPBase in later IOS releases?
Also I've seen conflicting specs on the max amount of Flash and DRAM the router can support. The following link shows that 384MB is the max for DRAM and 128MB max for flash. We're looking to upgrade ours from 128MB and 32MB respectively but as mentioned I've seen it where higher amounts are supported. In fact we bought a backup 1841 to have and it has a 256MB Flash card in it.URL
Last but not least. Where can I find a straightforward documention of this situation where we may have to upgrade our Flash and DRAM and then upgrading the IOS?
I have a cisco 1841 running on a 10Mbps Metro-E connection. I recently signed an agreement for a 100Mbps Metro-E. I am wondering if I will need to purchase a new router to support this new connection or will my 1841 be able to handle the traffic.

we are trying to configure 1841 with dual Internet connection with failover using track.
View 4 Replies View RelatedI decided recently to switch out our border router (1841 12.4 advsecurity) with a shiny new 1941 (15.2 SEC/K9) as the CPU upgrade was needed.The core below acts as a VPN end point to various other remote offices we have, all of which have a similar network design at each end (and all entirely managed by me). All of these are still running 1841's with 12.4 advsecurity on them as well. These are all GRE tunnels with ipsec procection on them (not crypto maps). [code]
Everything else works fine (NAT, route-maps etc), it's just these IPSEC/isakmp tunnels that are not playing ballIt's definitely not an ARP issue (all arps were cleared) and ICMP appears to work fine (ie, I can ping the remote tunnel's public IP endpoint from the core using the loopback for that tunnel as the source). I am suspecting it's something strange with the stateful firewall config, but I did try and apply ipsec and isakmp-msft to the ip inspect list, with no success.
