 If there are several IGMP groups in several VLANs, and the switch is acting as 

Querier, the switch may stop sending IGMP Queries on some of its VLANs.

■

 All Querier intervals on the switch will be cut in half if IGMP, after already being 

enabled, is disabled and then re-enabled.

■

The switch does not fully support 256 IGMP groups, as intended.  For example, 

with 15 VLANs and 40 IGMP groups, the 40th group gets flooded.  

■

 The MAX mode LED does not turn on for port where Gigabit Stacking Transceiver 

is installed.

■

If the "Send Authentication Traps" trap receiver parameter on 

a Member switch is set to "Yes", it will cause a memory leak on the Stack Commander switch. 
The memory leak can eventually cause a crash. The specific details of the crash vary.

■

 Port security learn mode and the learned MAC addresses are not saved 

after the switch is rebooted. 

■

 With port security on, the switch does not remember learned static MAC 

addresses after reboot. 

■

The commander may hang (SNMP, ping, TELNET, etc.) and other 

CPU functions may stop when the switch is queried by management applications such as the 
WhatsUp Gold utility.

■

If a commander has a CDP neighbor, the commander may run out 

of packet buffers and hang (SNMP, ping, TELNET, etc.).

■

 If a TELNET session times out due to the inactivity timer expiring, then a 

subsequent TELNET session will freeze at the switch's copyright screen, before displaying 
"Press any key to continue".  Note: This does not affect console sessions. 

■

 Unable to open new TELNET sessions due to switch not correctly closing 

previous TELNET sessions.

■

 Clicking the stack management close-up button does not show 

the 4108GL switch.
