Concept Guide

1 Following are some of the major protocols that can be dropped based on the FP rule entry, if those protocols are not congured or
blocked. All these drops are accounted as discard counters.
• LLDP BPDU redirects
• ARP
• STP/RSTP BPDU redirects
• BGP
• OSPF
• ECMP and LAG show cases
• VLT LLDP PDUs
• VLT DOT1x PDUs
• VLT PE ECP PDUs
• VLT IPM1 sync frames
• VLT ARP sync frames
• VLT TTL1 packets tunneled
• VLT ARP replies tunneled
• VLT STP BPDUs tunneled
• FEFD
• VRRP frames redirects
• ARP reply packets
• GVRP trac redirects
• LACP trac redirects
• Common VLT control frames
2 Packets are dropped due to user dened ACLs.
3 Multicast trac with the TTL value 1.
4 Multicast trac is not part of any group or special group that has to be processed by the CPU.
5 In addition to the above protocols, the lter processor rule also drops Yellow and Red packets if QoS is congured on the system.
