Configuring High Availability VLANs

High Availability VLANs Specifications

The table below lists specifications for high availability VLAN software.

RFCs Supported	2674—Definitions of Managed Objects for Bridges
	with Traffic Classes, Multicast Filtering and Virtual
	LAN Extensions

IEEE Standards Supported	802.1D—Media Access Control Bridges
	802.1w—Rapid Reconfiguration (802.1D Amend-
	ment 2)
	802.1s—Multiple Spanning Trees (802.1Q Amend-
	ment 3)

Maximum high availability VLANs per switch	32

Switch ports eligible for high availability VLAN	Fixed ports on second-generation Network Interface
assignment.	(NI) modules.

Switch port not eligible for high availability	Mobile, 802.1Q tagged, link aggregate, Learned Port
VLAN assignment.	Security (LPS), mirrored or mirroring ports, and all
	ports on first-generation NI modules.

Spanning Tree modes supported.	Flat (one Spanning Tree instance per switch).
	1x1 (one Spanning Tree instance per VLAN).

CLI Command Prefix Recognition	All high availability VLAN configuration commands
	with the vlan prefix support prefix recognition. (How-
	ever, the show mac-address-table port-mac com-
	mand does not support prefix recognition.) See the
	“Using the CLI” chapter in the OmniSwitch 7700/
	7800/8800 Switch Management Guide for more infor-
	mation.
