Supported APS MDA/Port Combinations
The following table displays examples of the port types that can be paired to provide APS
protection. Both ports must be the same type and must be configured at the same speed.
For example, an APS group can be comprised of a pair of ports where each port is on one of the
two following MDAs:
• m16-atmoc3-sfp
• m4-atmoc12/3-sfp (port in oc3 mode)
For example, an APS group can not be comprised of a pair of ports where one port is on an m16-
oc12/3-sfp and the other port is on an m1-choc12-as-sfp.
