Configuring SNMP parameters for serial console switches

SNMP is a protocol used to communicate management information between network management
applications and serial console switches. Other SNMP managers can communicate with your serial
console switch by accessing MIB-II and the public portion of the enterprise MIB. MIB-II is a standard MIB
that many SNMP servers support.
When you select the SNMP category for the first time, the Manage Console Switch window retrieves the
SNMP parameters from the unit. The SNMP category enables you to enter system information and
community strings, designate the management stations that can manage the serial console switch, and
retrieve SNMP traps from the serial console switch. If you select Enable SNMP, the unit responds to SNMP
requests over UDP port 161. Port 161 is the standard UDP port used to send and retrieve SNMP
messages.
NOTE:
console switches. For this reason, UDP port 161 must be open on firewalls. You must expose
UDP port 161 to monitor console switches through third-party SNMP-based management
software.
Up to four allowable managers can be defined, and all IP addresses are defined as blank by default. If
all four entries are left blank, all IP addresses are authorized to read and write to the serial console
switch, provided that they have the correct SNMP community strings. If any of the SNMP allowable
manager entries are not blank, then only the defined SNMP allowable managers have access.
The Manage Console Switch window uses SNMP within a secure tunnel to manage
