Workaround: The Legacy CLI is no longer supported in this release except for the
following command that allows you to implement a new
configuration to disable the power saving mode of the Phy chip
(refer to the Frames Transmitted with Cyclic Redundancy Check (CRC)
Errors section on page 3 under Known Problems and Workarounds:
> port set DisablePowerSave <port> on
Distance Vector Multicast Routing Protocol (DVMRP)
The switch may lose a small number of DVMRP neighbor-to-
neighbor probe messages which may cause multicast routing
instability under heavy loads.
IEEE 802.1Q
Packets
Problem: When a tagged IEEE 802.1Q packet arrives on a port that is set to
“bind-to-all” and the VLAN does not exist on the switch, the packet
is forwarded to that port’s default VLAN.
Workaround: To prevent unintended forwarding of unknown VLAN traffic to the
port’s default VLAN, configure the port default VLAN to “discard”.
* Note: Automatic VLAN creation does not work if the port default
VLAN is “discard”, because the switch does not learn this
VLAN.
Hunt Groups
■ Hunt groups can only consist of all layer 2 or all layer 3
modules. Hunt groups do not support a mixture of layer 2
and layer 3 modules.
■ When 48-port mode is enabled on the switch, you can
configure a maximum of thirteen hunt groups on the switch.
Link Status
When a large number of VLANs or endstations are on a hunt group,
it may take several seconds for the link status LED to change upon
failure.
