[c-nsp] Loss of Telnet Capability to 6509

[Richard J. Sears]

That is the interesting part. A Who shows a single connection on vty 2
(a sh line vty 2 seems to agree) but a clear line vty 2 (with a confirm)
fails to reset the line. The connection still shows active, however idle
for about 6 hours.


No other connections show open.
