Hi.

I have a cisco 1721 which is part of a network of many others cisco
1721. Suddenly I was unable to telnet it and a router replacement
didn't help. I can only telnet into it only by using vty 4. If I use
all the vty the telnet doesn't work. Then I have a couple of others
strange problems: I configured a password for the vty access, but when
I telnet successfully I immediately get access into the router and no
password is asked to me. Then, I can only write short commands. If I
write for example a general "show int" or a "show running-config", the
scroll of the data stops and never goes on after the first scroll.
I tried from different PC and I always got the same behaviour.

Follow a cut and paste of the vty line configuration and the
access-list 14 configuration:

line vty 0 3
access-class 14 in
exec-timeout 3 0
password xxx
logging synchronous
no login
escape-character 27
line vty 4
access-class 14 in
exec-timeout 3 0
timeout login response 60
password xxx
logging synchronous
login
escape-character 27

access-list 14 remark Controlled access via VTY Lines - Inbound
access-list 14 permit 10.252.240.0 0.0.3.255
access-list 14 permit 192.92.77.0 0.0.0.255
access-list 14 permit 192.92.22.0 0.0.0.255
access-list 14 permit 143.159.0.0 0.0.255.255
access-list 14 permit 146.198.0.0 0.1.255.255
access-list 14 permit 165.120.0.0 0.0.255.255
access-list 14 permit 213.31.20.0 0.0.3.255
access-list 14 permit 10.28.91.0 0.0.0.255
access-list 14 permit 10.28.110.0 0.0.0.255
access-list 14 permit 10.252.169.0 0.0.0.31
access-list 14 permit 10.252.169.64 0.0.0.31
access-list 14 permit 192.168.0.0 0.0.255.255
access-list 14 permit 204.231.0.0 0.0.255.255
access-list 14 permit 10.252.168.0 0.0.3.255
access-list 14 permit 10.252.232.0 0.0.3.255
access-list 14 permit 10.252.241.0 0.0.0.255

Thanks for your help,
Max

Why? That just says a password is not required.
