I don't believe that the information is encrypted. In most situations F5 recommends that you use a direct cable connection between members of an HA Pair and have all of your mirroring occurring on that interface.

Directly cable network mirroring interfaces

You can directly cable network mirroring interfaces on the BIG-IP systems in the failover pair, and F5 highly recommends that you do this when configuring a dedicated VLAN for mirroring. Configuring the pair in this way removes the need to allocate additional ports on surrounding switches, and removes the possibility of switch failure and switch-induced latency. Interfaces used for mirroring should be dedicated to the mirroring VLAN. Tagged interfaces shared with other VLANs could become saturated by traffic on other VLANs.
