Release Notes for ExtremeWare v6.2.1
No Static ARP Entries. The use of Static ARP entries associated with superVLANs or sub-VLANs is
not supported in this release (5106).
VLAN Aggregation and ESRP. A sub-VLAN should not be configured to run ESRP. The system will
allow you to enable ESRP on a VLAN and then designate the VLAN as a sub-VLAN, but this is not a
supported configuration (5193).
Multinetting
Multinetting and IP Multicast Routing. Combining any type of IP multicast routing on VLANs that
are also part of an IP multinetted group is not supported (4418).
Multinetting and Client Default Gateways. It is critical that clients attached to multinetted segments
have their default gateways correspond to the same subnet as their IP addresses and that subnet masks
be configured correctly. Not doing so will result in slow performance of the switch (4938).
Multinetting and the CLI Show VLAN Stats Command. The CLI “
show vlan stats <vlan_name>”
command is not supported on multinetted VLANs.
RIP Routing
RIP V2 Authentication
The authentication feature of RIPv2 is not supported.
RIP in Conjunction with other Routing Protocols
It is recommended that RIP be enabled only on routers running with less than 10,000 routes from other
routing protocols, such as BGP or OSPF.
Routing with OSPF
IP Multicast Routing and Snooping
Listed below are issues specific to running IP Multicast routing using PIMv2, DVMRP or IGMP
Snooping of IP Multicast traffic.
Cisco Interoperation
Note: For proper Cisco interoperation, you must run Cisco IOS version 11.3 or better, which
supports PIM 2.0. Cisco customer support also recommends using PIM in favor of DVMRP
whenever possible on Cisco routers (4669).
IGMP & IGMP Snooping with IP Unicast and Multicast Routing
IGMP snooping and IGMP must be enabled when unicast IP routing or multicast routing is configured
on the switch. By default, both IGMP and IGMP snooping are enabled. This can be checked using the
“
show ipconfig” command (5112).
