GARP VLAN
Registration Protocol
(GVRP)
GVRP (Generic Attribute Registration Protocol) VLAN Registration Protocol is a Layer 2
network protocol, for automatic configuration of switches in a VLAN network
DHCP Relay
Relay of DHCP traffic to DHCP server in different VLAN
Works with DHCP Option 82
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
Multicast VLAN
Registration (MVR)
MVR uses a dedicated manually-configured VLAN, called the multicast VLAN, to
forward multicast traffic over Layer 2 network in conjunction with IGMP snooping
Layer 3 Switching
IPv4 Static Routing
IPv4 Unicast: Static routing
IPv6 Static Routing
IPv6 Unicast: Static routing
Security
ACLs
Supports up to 512 entries. Drop or rate limitation based on:
Source and destination MAC, VLAN ID or IP address, protocol, port
Differentiated services code point (DSCP) / IP precedence
TCP/ UDP source and destination ports
802.1p priority
Ethernet type
Internet Control Message Protocol (ICMP) packets
TCP flag
Port Security
Locks MAC addresses to ports, and limits the number of learned MAC address
IP Source Guard
Prevents illegal IP address from accessing to specific port in the switch
Storm Control
Prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast
storm on a port
IEEE 802.1X
IEEE802.1X: RADIUS authentication, authorization and accounting, MD5 hash,
guest VLAN, single/multiple host mode and single/multiple sessions
Supports IGMP-RADIUS based 802.1X
Dynamic VLAN assignment
Supports authentication. Switch as a client
Secure Shell (SSH)
SSH secures Telnet traffic in or out of the switch; SSH v1 and v2 are supported
