SROS Command Line Interface Reference Guide HDLC Command Set

Syntax Description

No subcommands.

Default Values

By default, this command is disabled.

Command Modes

(config-interface)#	Interface Configuration Mode
	Valid interfaces include: Ethernet (eth 0/1), virtual PPP interfaces (ppp 1), virtual
	HDLC interfaces (hdlc 1), virtual Frame Relay sub-interfaces (fr 1.20), tunnel
	interfaces (tunnel 1), and VLAN interface (vlan 1).

Functional Notes

This command is used in IP multicast stub applications in conjunction with the ip mcast-stubhelper-address, ip mcast-stub upstream, and ip mcast-stub downstream commands. When enabled, the interface becomes a helper forwarding interface. The IGMP host function is dynamically enabled and the interface becomes the active upstream interface, enabling the unit to perform as an IGMP proxy.

Usage Examples

The following example sets the helper address as the IGMP proxy:

config)#interface hdlc 1

(config-hdlc 1)#ip mcast-stub helper-enable
