WIC status light? 3

[hinesjrh]

I have a new 2620XM router that I am setting up, so I do not currently have anything plugged into the WIC 1DSU-T1 V2 card. Please tell me if this looks / sounds correct. On the back of the WIC is an orange "AL" light (no other lights are lit) and in the config. the Serial0/0 interface shows "Serial0/0 is down, line protocol is down" Will that interface come "up" when the patch cable fro the smartjack is plugged in?

Here's some of the config that pertains to the interface:

interface Serial0/0
ip address 209.44.220.48 255.255.255.252
ip access-group 102 in
ip access-group 101 out
no ip mroute-cache
no fair-queue
service-module t1 timeslots 1-24
!
ip classless
ip route 0.0.0.0 0.0.0.0 Serial0/0
ip http server
!
access-list 101 deny udp any any eq 8998 log

When the patch is connected to the NIU the interface should come up. You may need to NAT traffic out that interface if you are not already doing that through a PIX or other firewall device. Also the default encap is HDLC...most telco use PPP for the encap. Check with them as to the correct encapsulation setting.

I would also recommend using the next hop IP address for the default route and not just the interface. lets assume the next hop is 209.44.220.47...set default route to:
ip route 0.0.0.0 0.0.0.0 209.44.220.47
This will keep the arp tables from becoming huge as it will only arp that subnet along with your internal subnet instead of everything that passes through it.

A couple of observations:

1. Joamon, the ARP issue would only apply if the exit interface were Ethernet. In this case it is a serial interface so the poster shouldn't run into that problem

2. Access list 101 has no permit statements so you're going to end up blocking all traffic, not just the UDP traffic to port 8998.

3. The encapsulation issue Joamon mentioned is important. If the encapsulation is wrong the circuit will still come up physically but you won't be talking at layer two or three.
