AT-S24 Version 2.2.2 Management Software Release Notes
PN 613-50247-00 Rev A 6 Allied Telesyn International
Telnet and Local Management Sessions
You cannot run both a Telnet and a local management session on a switch at the same
time. If you cannot establish a Telnet session to an AT-8200XL Series switch, someone else
might already be managing the switch locally, or the network administrator did not
properly quit from the last local management session on the switch. (Omega has a timeout
feature where it will automatically end a management session if it detects no management
activity after a specified period of time. The default setting is 5 minutes. This value is
adjustable. For instructions, refer to Chapter 7 in the AT-S24 Version 2.01 Users Guide.)
Configuring Port Mirroring Using an SNMP Network Manager
You can use an SNMP network manager to configure port mirroring. The MIB objects are
located as follows:
.alliedTelesyn(207)

You must set the following MIB objects:
