I've just replaced a 2610 router with a 3640 router supporting 2 T1 circuits. The configuration for the 3640 was copied from the 2610 (it's a very basic config). The 3640 is running IOS 12.1(1)T with
128MB RAM and 8MB flash.Telnet sessions TO the router (for remote management) are VERY slow. The cursor lags my typing to the point that I can't tell if it got the keystrokes or not for several (5-10) seconds. Responses from the router (say, from a show ver command) come back in chunks of text with
5-15 seconds between chunks.I'm also seeing intermittent ping response when I try to ping the FastEthernet0/0 port from either inside or outside my network; every other packet is dropped.
Traffic through the router is fine (http, ftp, telnet, ping, etc.). The problem seems to only be when I'm accessing the router itself.
Any ideas?
