Group mobility detailsGroup mobility details
AutoTracker supports 96 Groups with 32 VLANs / group
Group mobility adds a new capability to move between groups, rather than only within VLANs Groups are viewed as VLANs, so now we can
configure up to 500 VLANs (really groups) in the OmniSwitch
if there are no users active on the VLAN group then the if there are no users active on the VLAN group then the group is inactivegroup is inactive
when a user attaches and matches the policies, the when a user attaches and matches the policies, the group becomes activegroup becomes active

How does this all work?How does this all work?
The default group (Group #1) is used as a holding group for all ports participating in group mobility
AutoTracker rules operates the same; just use a AutoTracker rules operates the same; just use a group other than default Group #1 for AutoTracker if group other than default Group #1 for AutoTracker if you are also using group mobilityyou are also using group mobility
all ports on the default group are candidates to move all ports on the default group are candidates to move to one of the configured mobile groups to one of the configured mobile groups
groups now have a new group mobility flag groups now have a new group mobility flag if this flag is set the group is participating in group if this flag is set the group is participating in group

What is multicast traffic?What is multicast traffic?
Similar to broadcast traffic
It’s like selective broadcast
Only those that request the traffic get it
Allows a one to many communication rather than one to one

Why is IPMS so much better?Why is IPMS so much better?
IPMS (IP Multicast Switching):
intercepts IGMP intercepts IGMP packets to track packets to track membership by SVPN membership by SVPN (source virtual port (source virtual port number), rather than number), rather than by networkby network
client application client application requests membership requests membership in a multicast group; in a multicast group; only those members only those members will receive the will receive the multicast trafficmulticast traffic
Traffic is controlled by port rather than by network
Performance significantly improved because forwarding decision is made by network interface
All port forwarding lists are established dynamically; no configuration required
Co-exists with existing multicast VLANs

Why? to prevent IPX Watchdog packets from initiating to prevent IPX Watchdog packets from initiating
connections on dial-on-demand links when no other connections on dial-on-demand links when no other data is being sentdata is being sent
This feature will allow the Xylan router to respond to a server’s Watchdog requests on behalf of a remote client.

NetWare Serialization packet filtersNetWare Serialization packet filters
NetWare Serialization packet filtering: If serialization packet filtering is enabled on a WAN If serialization packet filtering is enabled on a WAN
interface, when the router receives a serialization interface, when the router receives a serialization packet, it will drop the packet instead of activating a packet, it will drop the packet instead of activating a dial-up linkdial-up link
