 Slow performance may occur when using 10/100 ports 

or  the 100FX transceiver operating at half-duplex.  This also may occur  when using 100FX, 
Gigabit Stacking, Gigabit-SX, or Gigabit-LX transceivers operating at full-duplex. Note: The 
Gigabit transceivers can only operate in full-duplex mode.  The Interpacket Gap (IPG) is too 
long for half-duplex and too short for full-duplex.  This may result in a switch crash with a 
message similar to:

 

 -> Software exception at woodyDma_recv.c:154 -- in 'eDrvPollRx'

  -> DMA unrecoverable error

■

 (PR_3138)  — A transceiver hot-swap is falsely reported when the 

screws on a transceiver are tightened or loosened.  

■

 (PR_3167)  — Removing and re-inserting both transceivers simultaneously 

many times with network cables attached and without an intervening reboot may cause the 
switch to crash with a message similar to:

  -> Software exception in ISR at buffers.c:1627

Release F.05.15 

(Beta Release Only)

Adds the following enhancements:

■

Increased IGMP V3 interoperability by allowing the switch to keep (and not prune) V3 groups. 
This lets the switch interoperate in an IGMP V3 environment without pruning off the V3 
groups (due to the Data-Driven IGMP feature) or always flooding.

■

Display the IGMP Querier in the output of the CLI 

show ip igmp command.

■

 Configuring broadcast limiting does not take effect until a reboot.

■

When CDP is disabled, the switch does not forward CDP packets.

■

 In the configuration file, the command: 

port-security 1 learn-mode continuous action send-alarm

results in this error message: 

Inconsistent Value

■

 In the configuration file, a command, such as: 

results in this error message: Inconsistent Value.

■

 Counters reset when you hot-swap a Gig-T transceiver.

■

 The Switch does not distinguish between CRC and alignment errors.
