Controller Ctrlr T1/E1

Recently I've been gathering in my work all cisco equipment which I can use to lab.

I have found few routers (2911, 1921, 1811), switches L3 (3750, 3560X) and L2 (2960, 2950) so I have got pretty nice stuff to do really good lab. I don't know what IOS ver are on these cisco stuff and if i will be able to set up BGP.Later I will check it.

I also have found few WIC cards which has been used to E1 connection :

VWIC2-1MFT-T1/E1   - one T1/E1 port

2 x VWIC2-2MFT-T1/E1  - two T1/E1 ports

I tried to install these WIC's on 1921 routers and it's not so easy as I thought.
When I turned on routers I saw WIC's in show version but I couldn't see them in show ip interface brief  and show run. 

R2#sho ver
Cisco CISCO1921/K9 (revision 1.0) with 487424K/36864K bytes of memory.
Processor board ID FCZ1513C46Q
2 Gigabit Ethernet interfaces
1 Serial interface
1 Channelized T1/PRI port
1 Virtual Private Network (VPN) Module
DRAM configuration is 64 bits wide with parity disabled.
255K bytes of non-volatile configuration memory.
250864K bytes of USB Flash usbflash0 (Read/Write)

It turned out we need to specify which card type we would like to use so in IOS :

R2#card type t1 0 0

 Next step we need to add a line to our controller config :

 controller T1 0/0/0
 cablelength long 0db
 channel-group 0 timeslots 1-24

Now I am able to see controller as a interface serial :

R2#sho ip int br
Interface                           IP-Address      OK? Method       Status                        Protocol
GigabitEthernet0/0             unassigned       YES unset            administratively down down
GigabitEthernet0/1             unassigned       YES unset            administratively down down
Serial0/0/0:0                      unassigned       YES unset            down                        down

I set up :

R1's serial0/0/0 ip address 172.17.0.1
R2's serial0/0/0 ip address 172.17.0.2

I also had to crossover cable. If you want to connect two T1 interfaces each other and use them as as serial interfaces you need to remember to crossover cable but not in standard way.

Finally I am able to ping from R2 to R1.

R2#sho ip int br
Interface                  IP-Address      OK? Method Status                Protocol
GigabitEthernet0/0         unassigned      YES unset  administratively down down
GigabitEthernet0/1         unassigned      YES unset  administratively down down
Serial0/0/0:0                 172.16.0.2        YES manual up                    up
R2#ping 172.16.0.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 ms

With these VWIC cards, my two 1921 have some extra ports that I can use in my lab.
