[xcat-user] configuring for stackable network switches...

[egan at sense.n. (E. Ford)]

There is a generic "switch" method that *should* work with all switches.
Look at $XCATROOT/samples/etc/switch.tab.  This generic method uses SNMP.

Richard -

The logic in xcat for the "cisco" method of getmacs is quite specific to
Cisco switches and will almost certainly have to be tweaked to work with
your SMC switches.

There are methods in /opt/xcat/lib for blackdiamond, cisco, and summit48i
switches, all of which use the same basic methodology, an expect script that
telnets to the switch and extracts the appropriate data from the arp table
in the switch. Working from these examples it shouldn't be hard to craft a
getmacs.smc8224 and getmacs.smc8224.expect.
