Using SNMP Tools To Manage the Switch

Configuring the Source IP Address for SNMP Notifications

The switch uses an interface IP address as the source IP address in IP headers when sending SNMP notifications (traps and informs) or responses to SNMP requests.

For multi-netted interfaces, the source IP address is the IP address of the outbound interface of the SNMP reply, which may differ from the destination IP address in the IP header of the received request. For security reasons, it may be desirable to send an SNMP reply with the IP address of the destination interface (or a specified IP address) on which the corresponding SNMP request was received.

To configure the switch to use the source IP address on which an SNMP request was received in SNMP notification/traps and replies, enter the snmp- server response-sourceand snmp-servertrap-sourcecommands.

Syntax: [no] snmp-server response-source [dst-ip-of-request <ipv4-addr ipv6- addr>]

Specifies the source IP address of the SNMP response PDU. The default SNMP response PDU uses the IP address of the active interface from which the SNMP response was sent as the source IP address.

The no form of the command resets the switch to the default behavior (compliant with rfc-1517).

Default: Interface IP address

dst-ip-of-request:Destination IP address of the SNMP request PDU that is used as the source IP address in an SNMP response PDU.

<ipv4-addripv6-addr>:User-defined interface IP address that is used as the source IP address in an SNMP response PDU. Both IPv4 and IPv6 addresses are supported.

For example, to use the IP address of the destination interface on which an SNMP request was received as the source IP address in the IP header of SNMP traps and replies, enter the following command:

ProCurve(config)# snmp-server response-source dst-ip-of-request
