boot configuration file (by using the command delete file), without first setting

a new preferred release or boot configuration file. Therefore, it was possible to

accidentally delete these files, which caused network disruptions if the router or

switch restarted. If the router or switch restarted after the user had deleted the

preferred release, it booted from the fallback software. Similarly, if the router or

switch restarted after the user had deleted the current boot configuration file, it

started up with no configuration.

This enhancement ensures that users can no longer delete the preferred software

release or the current boot configuration file. If you want to delete the files

without specifying new preferred files, first use the commands delete

install=pref or set config=none to stop the files from being preferred.

Stack

Object stackSnmpHost (at-stack.mib) is used to determine which stacked device

is currently responding to SNMP Requests. By setting the value of

stackSnmpHost, an SNMP manager can chose any one of the stacked switches

to poll. After a new value is set successfully, a new SNMP agent is chosen. On

SNMP V1 and V2c operations, the new agent is immediately ready to talk to the

manager. On SNMP v3 operations, the manager needs to re-run engine discovery

to re-synchronize the agent and manager.

Traps and notifications from stacked devices now include an extra object called

hostID, which gives the value of the switch’s host ID. This identifies which stacked

switch produced the trap or notification.
