Decoding Configuration

MPLS Parse

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)	nly support L2,EX,L3 default forward on CX102S
MPLS + ETH + (vlans) + IPV6	L2, EX, L3V6(src-mac, dst-mac, ethertype, src-ip, dst-ip, src-port, dst-port, ip-protocol)	nly support L2,EX,L3 default forward on CX102S

Inline Bypass

When auto bypass for inline bypass is enabled, the system will automatically monitor the LAG’s health status. At this point, the state of the bypass policy bound to the LAG is controlled by its health status and cannot be manually enabled or disabled: If the LAG remains down beyond the timeout period, the passthrough policy bound to the LAG will be activated. If the LAG remains up without flapping during the revert delay period (for standby LAGs, at least the minimum number of active ports must be up; for other types, at least one port must be up), the bypass policy bound to the LAG will be isabled, and traffic will revert to the original policy.

Operation	Command	Description
Enter system configuration view	configure
Open Inline Bypass	autobypass enable	Supports monitoring the status of serial-connected high reliability Lags: traffic switches to the bound passthrough policy upon Lag failure, and reverts to the original policy upon recovery.
