Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
To configure the switch to use a specified source IP address in generated trap
PDUs, enter the snmp-server trap-source command.
Syntax: [no] snmp-server trap-source [<ipv4-addr >]
Specifies the source IP address to be used for a trap PDU.
The no form of the command resets the switch to the default
behavior (compliant with rfc-1517).
Default: Use the interface IP address in generated trap PDUs.
<ipv4-addr >: User-defined interface IPv4 address that is used
as the source IP address in generated traps. IPv6 addresses
are not supported.
Notes When you use the snmp-server response-source and snmp-server trap-source
commands, note the following behavior:
â– The snmp-server response-source and snmp-server trap-source commands
configure the source IP address for IPv4 interfaces only.
â– You must manually configure the snmp-server response-source value if you
wish to change the default user-defined interface IP address that is used
as the source IP address in SNMP traps (RFC 1517).
â– The values configured with the snmp-server response-source and snmp-
server trap-source commands are applied globally to all interfaces that are
sending SNMP responses or SNMP trap PDUs.
â– Only the source IP address field in the IP header of the SNMP response
PDU can be changed.
â– Only the source IP address field in the IP header and the SNMPv1 Agent
Address field of the SNMP trap PDU can be changed.
To verify the configuration of the interface IP address used as the source IP
address in IP headers for SNMP replies and traps sent from the switch, enter
the show snmp-server command to display the SNMP policy configuration.
