Command History

This guide is platform-specific. For command information about other platforms, see the relevant Dell Networking OS Command Line Reference Guide.

Introduced on the Z9100-ON, S4048-ON, S6000-ON, S6100-ON, S4048T-ON, S3100, S6010-ON, S3048-ON, and C9010.
Usage Information
This command configures an expiration timer for all S.G entries, unless they are assigned to an Extended ACL.

Even though the FHR nodes act as RPs, these nodes still send Register encap messages to themselves and expect to receive a Register stop message (for Anycast RP support). As a result, if the DLT timer expires, SG is not deleted until the register state is deleted in the node. This register state expires 210 seconds after the last Null register is received.
