Decoding Configuration

2 min

In npb scenarios, some messages require the decoding switch to be turned on before five-element matching can be performed.

Table 1 MPLS decoding basic configuration

Operation	Command	Description
Enter system configuration view	configure
Enter npb configuration view	npb
Enable MPLS decoding	parse-over-mpls enable	Enables filtering of inner layer fields for MPLS/MPLS + PW messages.

After enabling MPLS decoding, the rule matching items supported by common MPLS packets are as follows

Table 2 Supported rule matching fields for MPLS packets

MPLS packets	Supported rule matching items	Description
MPLS + IPV4	L2, EX, L3(src-ip, dst-ip, src-port, dst-port, ip-protocol)
MPLS + ETH + (vlans) + IPV4	L2, EX, L3(src-mac, dst-mac, ethertype, src-ip, dst-ip, src-port, dst-port, ip-protocol)
MPLS + PW + ETH + (vlans) + IPV4	L2, EX, L3(src-mac, dst-mac, ethertype, src-ip, dst-ip, src-port, dst-port, ip-protocol)
MPLS + ETH + LACP	L2, EX, L3(src-mac, dst-mac, ethertype)
MPLS + IPV6	L2, EX, L3V6(src-ip, dst-ip, src-port, dst-port, ip-protocol)	Only support L2,EX,L3 default forward on CX102S
MPLS + PW + ETH + (vlans) + IPV6	L2, EX, L3V6(src-mac, dst-mac, ethertype, src-ip, dst-ip, src-port, dst-port, ip-protocol)
MPLS + ETH + (vlans) + IPV6	L2, EX, L3V6(src-mac, dst-mac, ethertype, src-ip, dst-ip, src-port, dst-port, ip-protocol)
