New Software Supported
OmniSwitch 6600/7000/8800—Release 5.1.5.R04 page 13
High Availability VLANs
High availability VLANs are now supported on OS7000 and OS8800 switches. High availability VLANs,
unlike standard Alcatel VLANs, allow you to send unicast and multicast traffic intended for a single desti-
nation MAC address to multiple switch ports within the same VLAN.
Note. IThis feature requires second generation (i.e., ENI-2, GNI-2) NI modules.
Increased IPX Routing Table Size
The size of the IPX routing table now supports up to 5000 entries. This is an increase from the previous
maximum of 2000 entries.
IPMS Enhancements
• IPMS is now supported with link aggregation.
• IGMP version 3 (IGMPv3), which handles forwarding by source IP address and IP multicast destina-
tion address, is now supported on OS7000 and OS8800 only. (IGMPv2 handles forwarding by IP
multicast destination address only.)
IP Routing Enhancements
The number of routing instances is changed from 64 to 128.
LACP Port Down Trap
A new trap has been added whereby a switch will send a trap when a single link in the aggregate group is
down or cannot join the aggregate group.
NTP Client Enhancements
The NTP client may now be configured to operate in broadcast mode. Broadcast mode specifies a client
switch listens on all interfaces for server broadcast timestamp information; it uses these messages to
update its time.
OS6600 Anti-spoofing ACLs
A new ACL enhancement has been added that will disable a port on 6600 series OmniSwitches when IP
spoofing is detected on the ports. By creating a new policy action called DisablePorts, ports will automati-
cally be administratively disabled when spoofed traffic is detected. The user may reset this state by
disconnecting and reconnecting their ethernet cable. See documentation for details and configuration
examples for this enhancement.
OS6600 Reboot Strategy
It is no longer necessary to reboot an entire OS6600 stack for synchronization of the configuration. Due to
this change the restore redundancy and show restore redundancy status commands have been deleted.
OS7700/7800/8800 Anti Spoofing ACLs
It is now possible to prevent IP source address spoofing using a new port group named UserPorts. Ports
placed in this special port group will block traffic whose source IP does not match the IP subnet config-
ured for that port. See documentation for details and configuration examples.
