cienaCesDpVirtualSwitchRlanMcastForwardingMode
Module: CIENA-CES-DATAPLANE-MIB
OID (symbolic): CIENA-CES-DATAPLANE-MIB::cienaCesDpVirtualSwitchRlanMcastForwardingMode
OID (numeric): 1.3.6.1.4.1.1271.2.1.7.1.8.2.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object specifies the virtual switch MCAST forwarding mode.
-'Default' follows a normal flooding path through the data-plane.
In this mode, frames with an L2 DA most-significant-byte equal to
0x01 are treated as all other ucast-flood and broadcast
traffic on the virtual switch.
-'l2Enhanced' provides increased performance for multicast L2 DAs
that have a most-significant-byte equal to 0x01, e.g., 01-??-??-??-??-??
What is cienaCesDpVirtualSwitchRlanMcastForwardingMode?
This INTEGER (default/l2Enhanced) decides how the switch handles frames whose destination MAC's most significant byte is 0x01, the range used by many multicast protocols. The 'default' mode treats them like ordinary broadcast or unknown-unicast flood traffic, while 'l2Enhanced' gives them a dedicated, more efficient forwarding path, a real performance choice on virtual switches carrying heavy multicast load like IPTV. Switching a virtual switch serving an IPTV deployment to l2Enhanced mode to improve multicast forwarding efficiency compared to treating every multicast frame like generic flood traffic is the practical use case.
