DESCRIPTION
This link takes you to screens where you can logically aggregate physical links to form one
logical and higher-bandwidth link.
This link takes you to a screen where you can copy traffic from one port or ports to another port
so that you can examine the traffic from the first port without interference.
This link takes you to a screen where you can configure port-based or IEEE 802.1p QoS. The
Switch can put packets into the queues according to the port on which the packet is received
or the priority tag in the packet.
This link takes you to a screen where you can configure IGMP snooping. You must enable IGMP
snooping to use the IPTV service. It checks the IGMP packets passing through it, picks out the
group registration information, and configures multicasting accordingly.
Traditionally, packets are transmitted in one of either two ways – Unicast (one sender to one
recipient) or Broadcast (one sender to everybody on the network). Multicast delivers packets
to just a group of hosts on the network.
This link takes you to screens where you can change the system login password, perform
firmware upgrade and configuration file maintenance as well as reset/reboot the system. You
can also configure the IP address and subnet mask, set management VID, and enable IEEE
802.3az EEE.
