4. Verify that the VLAN with ID 333 is tagged to Trk3. Enter:
HP ProCurve Switch 3500yl-24G# show vlan 333
Status and Counters - VLAN Information - Ports - VLAN 333

Trk3 Tagged Learn Up
VLAN 333 has been successfully tagged to Trk3.
On the server side, complete the following steps:
1. Create link aggregate lan900 using ports lan3 and lan4. Enter:
# nwmgr -a -S apa -A links=3,4 -I 900
Addition of links 3 4 to lan900 succeeded.
2. Create the VLAN with ID 333 over lan900. Enter:
# nwmgr -a -S vlan -A vlanid=333, ppa=900
VLAN interface lan5000 successfully configured.
lan5000 current values:
VPPA = 5000
Related PPA = 900
VLAN ID = 333
VLAN Name = UNNAMED
Priority = 0
Priority Override Level = CONF_PRI
ToS = 0
ToS Override Level = IP_HEADER
Configuring VLANs over failover groups
You can improve the availability of VLANs by configuring VLANs over a failover group. To ensure
success, each port (or link aggregate) used in the failover group must be tagged with the IDs of
the VLANs to be created over it. Before creating the failover group, you must decide the ports to
include in the failover group.
Figure 16 (page 94) shows the failover group lan902 consisting of LACP link aggregate lan901
as the active port with ports lan5 and lan6 as the standby ports. To protect against switch failures,
link aggregate lan901 is connected through Switch 1, and ports lan5 and lan6 are connected
to Switch 2. Switches 1 and 2 are connected to each other as well as the outgoing network. Two
VLANs, with IDs 333 and 334, operate over failover group lan902.
