Release Information

Statement introduced in Release 10.1 of Junos OS.

Description

Specify the redundant Ethernet interface, including its logical-unit-number, through which the monitored IP address must be reachable. The specified redundant Ethernet interface can be in any redundancy group. Likewise specify a secondary IP address to be used as a ping source for monitoring the IP address through the secondary node’s redundant Ethernet interface link.

Options

rethX.logical-unit-number—Redundant Ethernet interface through which the monitored IP address must be reachable. You must specify the redundant Ethernet interface logical-unit-number. Note that you must also configure a secondary ping source IP address (see below).

Range: reth0.logical-unit-number through reth128.logical-unit-number (device dependent)

secondary-ip-address IP–address—Specify the IP address that will be used as the source IP address of ping packets for IP monitoring from the secondary child link of the redundant Ethernet interface. An IP address for sourcing the ping packets on the primary link of the redundant Ethernet interface must be configured before you can configure secondary-ip-address. For legacy support reasons, monitoring on an IP address without identifying a redundant Ethernet interface and without configuring a secondary ping source IP address is permitted but not recommended.

Usage Guidelines

For configuration instructions and examples, see the Junos OS Security Configuration Guide.
