Troubleshooting the TMS zl Module in Routing Mode
The logs show numerous broadcast messages on VLAN 1, but you
have not configured VLAN 1 as a TMS VLAN.
HA cluster members communicate on the HA VLAN, which is configured
on each member’s internal port 2, and by default, the HA VLAN is VLAN
1. The TMS zl Module receives broadcast traffic on the HA VLAN whether
or not you configure HA.
For this reason, ProCurve recommends that you set the HA VLAN to a
VLAN that is not already being used on your network. Otherwise, the TMS
zl Module receives broadcast traffic that the firewall must drop—which
can cause an undue number of log messages. (You should change the HA
VLAN even if you are not using HA.)
You can change the HA VLAN from either the CLI or the Web browser
interface. If you change it from the CLI, you can change just the VLAN. If
you configure HA from the Web browser interface, you must change the
VLAN and configure an IP address for that VLAN.
