links are in separate VLANs. However, you can use port trunking to prevent
Spanning Tree from unnecessarily blocking ports (and to improve overall
network performance). Refer to "RSTP and STP Operation with 802.1Q
VLANs" on page 5-9.
Note that Spanning Tree operates differently in different devices. For exam­
ple, in the (obsolete, non-802.1Q) ProCurve Switch 2000 and the ProCurve
Switch 800T, Spanning Tree operates on a per-VLAN basis, allowing redundant
physical links as long as they are in separate VLANs.

IP Interfaces

There is a one-to-one relationship between a VLAN and an IP network inter­
face. Since the VLAN is defined by a group of ports, the state (up/down) of
those ports determines the state of the IP network interface associated with
that VLAN. When a VLAN comes up because one or more of its ports is up, the
IP interface for that VLAN is also activated. Likewise, when a VLAN is
deactivated because all of its ports are down, the corresponding IP interface
is also deactivated.

VLAN MAC Addresses

Some switch models use the same MAC address for all configured VLANs,
while other switch models use a different MAC address for each configured
VLAN.

You can send an 802.2 test packet to the VLAN MAC address to verify
connectivity to the switch. Likewise, you can assign an IP address to the VLAN
interface, and when you Ping that address, ARP will resolve the IP address to
this MAC address. (Refer to table 2-1 on page 2-4 for the maximum number of
VLANs allowed on your switch).
