QCE# Indicates the index of QCE
Frame Type
Indicates the type of frame to look for incoming frames. Possible frame
types are:
Any : the QCE will match all frame type.
Ethernet : Only Ethernet frames (with Ether Type 0x600-0xFFFF) are
allowed.
LLC : Only (LLC) frames are allowed.
SNAP : Only (SNAP) frames are allowed.
IPv4 : the QCE will match only IPV4 frames.
IPv6 : the QCE will match only IPV6 frames.
Port Indicates the list of ports configured with the QCE.
Action
Indicates the classification action taken on ingress frame if parameters
configured are matched with the frame's content.
There are three action fields: Class , DPL , and DSCP .
Class : Classified QoS; if a frame matches the QCE, it will be put in the
queue.
DPL : Drop Precedence Level; if a frame matches the QCE, then DP
level will set to a value displayed under DPL column.
DSCP : if a frame matches the QCE, then DSCP will be classified with
the value displayed under DSCP column.
Conflict
Displays the conflict status of QCL entries. As hardware resources are
shared by multiple applications, resources required to add a QCE may
not be available. In that case, it shows conflict status as Yes , otherwise
it is always No . Please note that conflict can be resolved by releasing
the hardware resources required to add the QCL entry by pressing
Resolve Conflict button.
5.7 Multicast
5.7.1 IGMP Snooping
IGMP (Internet Group Management Protocol) snooping monitors the IGMP traffic between
hosts and multicast routers. The switch uses what IGMP snooping learns to forward multicast
traffic only to interfaces that are connected to interested receivers. This conserves bandwidth
by allowing the switch to send multicast traffic to only those interfaces that are connected to
hosts that want to receive the traffic, instead of flooding the traffic to all interfaces in the VLAN.
This page allows you to set up IGMP snooping configurations.
