I want to run/setup FrameRelay in my home lab. I've the following routers,
3640,2611,2501 & 1700.
I want 3640 to be my Frameswitch, however it doesn't have Serial interface, so i wanted to buy it & that's where i got confused. Following are the serial modules available for 36xx series. which one should I go for?
NM-16A - 16 port high-density async network module
NM-32A - 32 port high-density async network module
NM-4T - Four-port serial network module.
NM-4A/S - Four-port async/sync serial network module.
I believe for FrameRelay we can use any router with 2 or more serial interfaces (for more connectivity). Im new, if its wrong, correct me please...
I've following Serial Interface on my Cisco routers.
1/ Cisco 2621 -
a) Module - VWIC-2MFT-T1-DI
b) Fractional T1 - DSU/CSU
2/ Cisco 3640 -
a) NM-4T - Four-port serial network module. (as Giuseppe said, I ordered that module).
b)Module - VWIC-2MFT-T1-DI
3/ Cisco 2501
a) Two Serial ports (RS232 type)
4/ Cisco 1700
a) Fractional T1 - DSU/CSU
I want to make my 3640 as FrameSwtich, so can i connect DCE-DTE (RS232) cable to 2501; & RJ 45 type cable to 1700 and 2611 ? Will that work? Bottom line is I want connectivity to all 3 routers from 3640, for testing frame relay.
So .. the VWIC in the 3640 can connect to the 1700 and the 2621 with T1 crossover cables (1,2 -> 3,5) and the NM-4T will need the 60 pin D crossover DCE-DTE cables. That leaves on port available on the 2621 .. unless your configuring Drop and Insert on the VWIC, then the additonal port will be necessary. Cool. Looks good.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
