IGMP v1/v2/v3
Snooping
IGMP limits bandwidth-intensive multicast traffic to only the requesters. Supports 1024
multicast groups
IGMP Querier
IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the
absence of a multicast router
IGMP Proxy
IGMP snooping with proxy reporting or report suppression actively filters IGMP packets
in order to reduce load on the multicast router
MLD v1/v2 Snooping Delivers IPv6 multicast packets only to the required receivers
Quality of Service
(QoS)
Support 8 hardware queues.
Scheduling: Strict priority and WRR, Queue assignment based DSCP and class of
service
Classification: Port based, 802.1p VLAN priority based, IPv4/IPv6 precedence/ DSCP
based, DiffServ, Classification and re-marking ACLs
Rate Limiting: Ingress policer, Egress shaping, rate control and per port
CFM
Connectivity Fault Management (CFM) is an IEEE 802.1ag and ITU Y.1731 standard
for managing connectivity at the Ethernet service level.
APS
Ethernet Automatic Protection Switching (APS) is a linear protection scheme designed
to protect VLAN based Ethernet networks.
Keychain
A keychain is a sequence of keys that provides dynamic authentication to ensure
secure communication by periodically changing the key and authentication algorithm
without service interruption. When the system time is within the lifetime of a key in a
keychain, an application uses the key to authenticate incoming and outgoing packets.
The keys in the keychain take effect one by one according to the sequence of the
configured lifetimes. In this way, the authentication algorithms and keys are
dynamically changed to implement dynamic authentication.
