Hi Cisco Gurus,
I'm busy with the replacement of a C2501 by a C2610 with a 4 Serial in Slot1.
Cisco is connected to a 7206. I just replaced the C2501 with the C2610
and plugged the same cables etc... (both router have the same IP, routes, ...)
Problem: The line is up but the protocol is going up/down every mins.
I also get a very high numbers of errors! Any idea?
On the 7206:
Serial4/0 is up, line protocol is up
Hardware is M4T
Interface is unnumbered. Using address of FastEthernet0/0 (a.b.c.d)
MTU 1500 bytes, BW 512 Kbit, DLY 20000 usec, rely 185/255, load 1/255
Encapsulation HDLC, loopback not set, keepalive set (10 sec)
Last input 00:00:04, output 00:00:00, output hang never
Last clearing of "show interface" counters 00:39:11
Input queue: 0/75/0 (size/max/drops); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/64/0 (size/threshold/drops)
Conversations 0/258 (active/max active)
Reserved Conversations 0/0 (allocated/max allocated)
5 minute input rate 2000 bits/sec, 3 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec

Received 0 broadcasts, 0 runts, 4 giants
3619 input errors, 954 CRC, 0 frame, 0 overrun, 0 ignored, 2665 abort

0 output errors, 0 collisions, 57 interface resets
0 output buffers copied, 0 interrupts, 0 failures
