I'll try using SNMP for getting the ARP tables. I'll have to move the
code to the one machine at our site that is allowed to query switches
and routers via SNMP.
I'm still looking for something that will obtain the equivalent of:
show mac-addr dynamic
on C3550 switches (not the same as the C2900XL/C3500XL switches)
and
show cam dynamic
on C6509 switches
Having had a fair bit of grief getting the right data out of C3550's,
using a Kermit script is looking attractive.
Regards,
Arthur.
