Switch Features
71
The FCoE Initialization Protocol (FIP) is used to perform the functions of
FC_BB_E device discovery, initialization, and maintenance as defined in the
ANSI T11 FC-BB-5 specification. The PCM8024-k switch supports FIP
snooping, which is a frame inspection method used by FIP Snooping Bridges
to monitor FIP frames and apply policies based upon the L2 header
information in those frames. For information about configuring the FIP
Snooping feature, see "Configuring Data Center Bridging Features" on
page 837.
Cisco Protocol Filtering
The Cisco Protocol Filtering feature (also known as Link Local Protocol
Filtering) filters Cisco protocols that should not normally be relayed by a
bridge. The group addresses of these Cisco protocols do not fall within the
IEEE defined range of the 802.1D MAC Bridge Filtered MAC Group
Addresses (01-80-C2-00-00-00 to 01-80-C2-00-00-0F).
For information about configuring LLPF, settings see "Configuring Port-
Based Traffic Control" on page 687.
DHCP Layer 2 Relay
This feature permits Layer 3 Relay agent functionality in Layer 2 switched
networks. The switch supports L2 DHCP relay configuration on individual
ports, link aggregation groups (LAGs) and VLANs.
For information about configuring L2 DHCP Relay settings see "Configuring
L2 and L3 Relay Features" on page 931.
Virtual Local Area Network Supported Features
For information about configuring VLAN features see "Configuring VLANs"
on page 561.
VLAN Support
VLANs are collections of switching ports that comprise a single broadcast
domain. Packets are classified as belonging to a VLAN based on either the
VLAN tag or a combination of the ingress port and packet contents. Packets
sharing common attributes can be groups in the same VLAN. The
PowerConnect M6220, M6348, M8024, and M8024-k switches are in full
compliance with IEEE 802.1Q VLAN tagging.
