Wireshark-users: Re: [Wireshark-users] Capturing VLAN tags with Wireshark

Steve,
The 2924-XL does have the ability to monitor ports but you may be out of
luck since you cannot monitor trunks on this switch only a vlan on a
trunk.  See the following url.

Apparently, Cisco says port monitoring is available through the web
browswer but I've never tried it:

The Catalyst 2924M XL features the Cisco Web-based management tool,
Cisco Visual Switch Manager (CVSM), which allows network administrators
to view and manage the switch from anywhere on the network through a
standard browser such as Microsoft Internet Explorer or Netscape
Navigator. Launched from the switch itself, CVSM delivers simple
network- and device-level management, including port configuration, VLAN
setup, network views, and port monitoring. CVSM is an integral part of
the Cisco scalable stacking architecture, allowing users to easily
configure and manage stacks and switch clusters and to administer
software upgrades across multiple switches.

Thanks for the advice, however this particular switch is a 2924-XL, and
it does not appear to have the monitor command in config mode.

I guess if I really want to do this, I'll either have to replace the
switch, or trunk out of the switch through an inline filter and to the
destination router.

Thanks anyway,

Steve
