NOOPING
Support IGMP version 2 (RFC 2236): The function IGMP snooping is
used to establish the multicast groups to forward the multicast
packet to the member ports, and, in nature, avoid wasting the
bandwidth while IP multicast packets are running over the network.

The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC and
VLAN parameters etc. Here we will just go over the standard and
extended access lists for TCP/IP. As you create ACEs for ingress
classification, you can assign a policy for each port, the policy
number is 1-8, however, each policy can be applied to any port.
This makes it very easy to determine what type of ACL policy you
will be working with.

UTHENTICATION
This switch provides management access via the console port,
Telnet, or a web browser. User names and passwords can be
configured locally or can be verified via a remote authentication
server (i.e., RADIUS or ).
Port-based authentication is also supported via the IEEE
802.1X
protocol. This protocol uses Extensible Authentication Protocol over
LANs (EAPOL) to request user credentials from the 802.1X client,
and then uses the EAP between the switch and the authentication
server to verify the client‘s right to access the network via an
authentication server (i.e., RADIUS server).
Other authentication options include HTTPS for secure management
access via the web, SSH for secure management access over a
Telnet-equivalent connection, SNMP Version 3, IP address filtering
for web/SNMP/Telnet/SSH management access, and MAC address
filtering for port access.

P
ROXY The implementation of IP multicast processing. The switch supports IGMP
version 1 and IGMP version 2, efficient use of network bandwidth, and fast
response time for channel changing. IGMP version 1 (IGMPv1) is described in
RFC1112 ,and IGMP version 2 (IGMPv2) is described in RFC 2236. Hosts
interact with the system through the exchange of IGMP messages. Similarly,
when you configure IGMP proxy, the system interacts with the router on its
upstream interface through the exchange of IGMP messages. However, when
acting as the proxy, the system performs the host portion of the IGMP task on
the upstream interface as follows:

When queried, sends group membership reports to the group.

When one of its hosts joins a multicast address group to which
none of its other hosts belong, sends unsolicited group
membership reports to that group.

When the last of its hosts in a particular multicast group leaves the
group, sends an unsolicited leave group membership report to the
all-routers group (244.0.0.2).
