keepalive c e s On SONET interfaces, send keepalive packets periodically to keep an interface alive when it is not transmitting data. Syntax keepalive [seconds] To stop sending SONET keepalive packets, enter no keepalive. Parameters seconds (OPTIONAL) For SONET interfaces with PPP encapsulation enabled, enter the number of seconds between keepalive packets. Range: 0 to 23767 Default: 10 seconds Defaults Enabled Command Modes INTERFACE Command History Version 8.3.3.1 Version 8.1.1.2 Version 7.6.1.0 Version 7.5.1.0 pre-Version 6.2.1.0 Introduced on the S60. Introduced on E-Series ExaScale Introduced on S-Series Introduced on C-Series Introduced for E-Series Usage Information When you configure keepalive, the system sends a self-addressed packet out of the configured interface to verify that the far end of a WAN link is up. When you configure no keepalive, the system does not send keepalive packets and so the local end of a WAN link remains up even if the remote end is down. lfs enable e Enable Link Fault Signaling (LFS) on 10 Gigabit Ethernet interfaces only. Syntax lfs enable To disable LFS, enter no lfs enable. Defaults Enabled. Command Modes INTERFACE (10 Gigabit Ethernet interfaces only) Command History pre-Version 6.1.1.0 Introduced for E-Series Usage If there is a failure on the link, FTOS brings down the interface. The interface will stay down until the Information link failure signal stops. Note: On TeraScale line cards, LFS is always enabled by default. Interfaces | 457
