IPv4)
src-mac-address ( MAC address ; default: 00:00:00:00:00:00 ) - source MAC address
src-port ( integer : 0 ..65535 ) - source port number or range (only for TCP or UDP protocols)
stp-flags ( topology-change | topology-change-ack ) - The BPDU (Bridge Protocol Data Unit)
flags. Bridge exchange configuration messages named BPDU peridiocally for preventing from loop
• topology-change - topology change flag is set when a bridge detects port state change, to force
all other bridges to drop their host tables and recalculate network topology
• topology-change-ack - topology change acknowledgement flag is sen in replies to the
notification packets
stp-forward-delay ( time : 0 ..65535 ) - forward delay timer
stp-hello-time ( time : 0 ..65535 ) - stp hello packets time
stp-max-age ( time : 0 ..65535 ) - maximal STP message age
stp-msg-age ( time : 0 ..65535 ) - STP message age
stp-port ( integer : 0 ..65535 ) - stp port identifier
stp-root-address ( MAC address ) - root bridge MAC address
stp-root-cost ( integer : 0 ..65535 ) - root bridge cost
stp-root-priority ( time : 0 ..65535 ) - root bridge priority
stp-sender-address ( MAC address ) - stp message sender MAC address
stp-sender-priority ( integer : 0 ..65535 ) - sender priority
stp-type ( config | tcn ) - the BPDU type
• config - configuration BPDU
• tcn - topology change notification
vlan-encap ( 802.2 | arp | ip | ipv6 | ipx | rarp | vlan ) - the MAC protocol type encapsulated in the
VLAN frame
vlan-id ( integer : 0 ..4095 ) - VLAN identifier field
vlan-priority ( integer : 0 ..7 ) - the user priority field
Notes
stpmatchers are only valid if destination MAC address is 01:80:C2:00:00:00/FF:FF:FF:FF:FF:FF
(Bridge Group address), also stp should be enabled.
ARP matchers are only valid if mac-protocol is arp or rarp
VLAN matchers are only valid for vlan ethernet protocol
IP-related matchers are only valid if mac-protocol is set as ipv4
802.3 matchers are only consulted if the actual frame is compliant with IEEE 802.2 and IEEE 802.3
standards (note: it is not the industry-standard Ethernet frame format used in most networks
worldwide!). These matchers are ignored for other packets.
