SXP Protocol Exchange

A.

SXP (Security Group Tag Exchange Protocol) is a protocol used for sharing Security Group Tag (SGT) information between network devices. SGT is a tag that is assigned to a packet by a source device to identify the security group that the packet belongs to. The SXP protocol allows network devices to share SGT information to enforce security policies based on security groups instead of IP addresses.

When two SXP peers establish a connection, they exchange IP to SGT binding information. This means that each device shares information about which IP addresses belong to which security groups. This information is then used to apply security policies based on SGTs instead of IP addresses.

Therefore, the answer to this question is A. The SXP protocol exchanges IP to SGT binding information between peers.

Option B, MAC to SGT binding information, is incorrect. SXP does not exchange MAC to SGT binding information.

Option C, ingress port to SGT binding information, is incorrect. SXP does not exchange ingress port to SGT binding information.

Option D, ingress switch to SGT binding information, is also incorrect. SXP does not exchange ingress switch to SGT binding information.
