Copper Gigabit SFP Support on OmniSwitch 6600 Family
In release 5.1.6.R01 and later, copper Gigabit SFPs are now supported on OmniSwitch 6600 Family
switches. These SFPs can be used with the built-in Gigabit uplink slots on the OS6602-24 and OS6602-48
switches and on the OS6600-GNI-U2 uplink submodule.
Note. Copper Gigabit SFPs on OmniSwitch 6600 Family switches support 1000 Mbps and full duplex.
They do not support 10 or 100 Mbps speeds or half duplex mode.
Configurable Flood Queue Bandwidth for High Availability VLANs
The ingress flood queue bandwidth size for high availability VLANs is now a configurable value. By
default, the bandwidth size is 15 Mbps and can be set to a maximum of 1000 Mbps with a minimum of 1
Mbps. This queue is created when the first high availability VLAN becomes active and is removed when
the last high availability VLAN is deleted.
DoS Phase 1
The Alcatel DoS trap has been enhanced so that it now provides the source address of the device perform-
ing the DoS attack. This is particularly useful for OmniVista.
A trap will be generated if configured on the switch to indicate an offensive device.
EtherType Prioritization
A new QoS policy condition is now available to classify and prioritize traffic based on EtherType. When a
rule is created and applied using this new condition, traffic containing the specified EtherType is identi-
fied and then queued to a higher priority queue.
Note. This feature is not supported on traffic received with an 802.1Q tag.
Fixed Management IP Address for Traps
One single IP address of a switch with multiple routed VLANs is now used as the source IP address sent
on every SNMP request or trap. When a trap is sent from the switch, the source IP address is the same as
the IP address configured by the ip router router-id command. If no address is configured by the ip
router router-id command, then the default value for router-id will be the primary IP address of the
VLAN with the lowest VLAN identifier.
Note. You cannot remove the ip router router-id from CLI. You need to delete the line from the boot.cfg
and reboot the switch.
Generic UDP Relay
In addition to BOOTP/DHCP relay, generic UDP relay is now available on OmniSwitch 6600 switches.
Using generic UDP relay, traffic destined for well-known service ports (e.g., NBNS/NBDD, DNS, TFTP,
and TACACS) or destined for a user-defined service port can be forwarded to a maximum of 256 VLANs
on the switch.
