[c-nsp] VTY locks on show commands

[Voll, Scott]

Thanks to everyone who helped......

It ended up being a Telco problem.  Something about a protocol
mismatch...... Kind of like a half / full duplex issue with Frame-relay
/ ATM.

Thanks again all

Scott

Well, the ATM side should happily work with whatever MTU you configure,
as long as both sides are the same (telco never sees the full packet,
only ATM cells).

The ATM FR interworking might be a problem, with the ATM side defaulting
to an MTU of 4470 and the FR side being Telco-limited to 1500 (or 
whatever).

For transit traffic coming via Ethernet into the router, this is not
a problem (as the packets are already "small") - but for traffic
generated
*by* the router, it might be.

Try putting:

     ip mtu 1500

(or plain "mtu 1500") in here.

... and for symmetry, do the same on this side (dunno what the default
MTU for FR interfaces is).
