A leaky port is allowed to access other ports for various applications such as security, network control, and management. Note: When both isolation and leakage are applied to the same port, the port is isolated. Isolated/leaked ports. Lookup type of the isolation/leakage entry: - src - Entry applies to ingress packets of the ports. - dst - Entry applies to egress packets of the ports. Matching traffic forwarding type on Cloud Router Switch. Matching traffic type. Registration status for matching packets. Known ones are present in UFDB and MFDB, and unknown ones are not. Included protocols for isolation/leakage. Matching MAC isolation/leakage profile. Matching Port isolation/leakage profile. Matching VLAN isolation/leakage profile.
