Static Virtual LANs (VLANs)

Port-Based Virtual LANs (Static VLANs)

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).
