Module: ZYXEL-MLD-SNOOPING-PROXY-MIB

OID (symbolic): ZYXEL-MLD-SNOOPING-PROXY-MIB::zyMldSnoopingProxyDownstreamVlanPortLeaveMode

OID (numeric): 1.3.6.1.4.1.890.1.15.3.51.3.8.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Leave mode for the port. When a done report is received, downstream sends MASQ to confirm a multicast address has no listener. Once the MASQ is timeout, the multicast group is deleted. This entry handle the mode of deleting a multicast address. Immediate : when a done report is received, a multicast address is immediately deleted. Fast: a timer for wating a response of a MASQ, and a multicast address is deleted when the timer is timout. Normal: a timer for wating a response of a MASQ, and a multicast address is deleted when the timer is timout.

What is zyMldSnoopingProxyDownstreamVlanPortLeaveMode?

Controls how this downstream port handles a host's Done (leave) message: immediate(0) deletes the multicast address entry right away; normal(1) and fast(2) instead start a timer waiting for a Multicast-Address-Specific Query (MASQ) response and only delete the entry when that timer expires. Fast is used for hosts known to respond quickly, cutting leave latency versus normal mode.
