Changes and Enhancements in 2.01.22
A new enhanced buffer mode function is available, which allows a standalone switch to support maximum
buffers in its default tran
smit queues. Six of the available transmit queues are not set as ―default‖ and the
remaining 2 queues are reserved for higher priority tagged traffic. This function can be enabled or disabled using
the ―set system enhancedbuffermode enable | disable‖ command from admin access mode. When the set
command is issued, the unit will prompt before resetting and rebooting in enhanced buffer mode. Default state is
disabled. Current state can be displayed using ―show system enhancedbuffermode‖ or ―show config‖.
Important: Units must be operating as standalone switches when running in enhanced buffer mode.
Stacking in this mode is not supported.
A new ―save config‖ command is now available This saves the running configuration on all stack members.
The FDB age time can now be set using the dot1dTpAgingTime MIB.
A problem causing the switch to actively reply when Telnet is disabled has been resolved.
A problem causing the switch to send a page stating Webview is disabled has been resolved.
An OID has been implemented
in the switch which can be polled via SNMP to return the switch‘s default
gateway IP.
A problem with setting the IP address on the switch, which caused an additional IP destination to be seen until
the switch is reloaded, has been resolved.
An SNTP UTC offset for log time stamps is now supported.
A problem with the C2G134-24P units displaying the wrong sysObjectId has been resolved.
A problem causing all LEDs to be affected when a MGBIC was installed on a C2G134-24P device has been
resolved.
Changes and Enhancements in 2.01.20
The command ―show switch stack-port‖ has been added to allow a user to view various data flow and error
counters on stack ports.
GVRP is enabled globally, but disabled on all ports by default. It is recommended that users enable GVRP on
inter-switch links (ISLs), and leave it disabled on all other edge ports within the stack. Large numbers of ports
with large numbers of VLANs can consume a large amount of CPU process time, causing the device to drop
dynamic VLANs.
It is recommended that users do not create rules which use priority 7. The protocol packets which keep the stack
integrity use priority 7 and high amounts of traffic with this priority setting may affect stack resiliency.
Unit buffers have been optimized to improve stack throughput for transfers using large block sizes.
A problem with the ―set SNMP access‖ has been corrected.
A problem preventing LAG creation if non-default adminkey was changed has been corrected.
A problem with the advertised ability MIB not being persistent has been corrected.
A problem causing the inability to set SNMPv3 targetparams has been corrected.
A problem causing the C2G124 to not link up when auto-negotiation was disabled has been corrected.
A problem with unlearned unicast packets preventing the stack from linking up has been corrected.
A problem with modules not supporting static trunking has been corrected.
A problem with the ―set length 20‖ command not working with ―show config‖ has been corrected.
A problem causing the inability to disable IGMP via CLI interface mode has been corrected.
Changes and Enhancements in Previous Releases
The ―show slot‖ command found in previous images has been changed to ―show switch hardware‖ to follow the
syntax of other CLI commands.
Beginning with the 2.00.xx release the C2 family supports Enterasys Secure Networks capability. This includes
support of user policies.
Configuration of Node/Alias is supported via both MIBs and CLI, however display of the Node/Alias table is
limited to SNMP only.
Spanning Tree and Link Aggregation Group commands are now available via the CLI.
MAC port locking is supported in this release. However, support is limited to dynamically learned addresses
only. Static locking will be supported in a future release.
The ―DiffServ‖ functions supported in previous releases have been removed.
