21 Interswitch Protocols
This chapter describes Interswitch Protocols, which are used to discover adjacent switches,
and track
VLAN membership and retain mobile group information across switches. They
include two new protocols and one existing protocol that is updated for release 4.0:
• Mapping Adjacency Protocol ( XMAP ), a new protocol used to discover the topology of
Omni Switch/Routers (Omni S/Rs)
• Group Mobility Advertisement Protocol ( GMAP ), a new protocol used to retain learned
mobile group and protocol information
• VLAN Advertisement Protocol ( VAP ), an existing interswitch protocol used to exchange
VLAN information between switches
The protocols are independent of each other and perform separate functions. Each protocol is
described in detail in separate sections of this chapter.
