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:

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.
