Question : Upgrading from Cisco 3640 to Cisco 3625
|
|
I am in the process of replacing a Cisco 3640 with a Cisco 3825 and am having trouble with the configuration on the 3825. Below is my current configuration on the 3640 and the startup config for the 3825. Could someone please help me figure out how to get the config working on the 3825? Any help would be greatly appreciated.

Answer : Upgrading from Cisco 3640 to Cisco 3625
|
|
Well, first major problem I see is that the 3825 has no ATM cards to handle the existing ones on the 3640...
The rest of it should be pretty straight forward...
Both the Ethernet Interfaces should be able to go straight over (assuming those are 10/100/1000 or you have Gig-E ports on whatever they're connected to)
The T1's are done a little differently, first you create the channel-group on the controller then you'll have a new serial interface appear with a channel group tacked on to the end.
We'll use Serial0/0 as the example for the 3825:
---1st config the controller with the channel group (0 in this case)---
controller T1 0/0/0
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24
Now you'll have a new serial interface Serial0/0/0:0, so create the serial config as you would normally:
interface Serial0/0/0:0
bandwidth 1536
ip address 111.111.112.1 255.255.255.252
no ip mroute-cache
load-interval 30
no fair-queue
Same thing would apply on your existing Serial0/1:
controller T1 0/0/1
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24
!
interface Serial0/0/1:0
bandwidth 1536
ip address 111.111.113.1 255.255.255.252
no ip mroute-cache
load-interval 30
no fair-queue
The rest of your routing info should be able to copy straight over as well.
