We have seen in 12.2.18SXF12 (maybe also available in earlier releases) that the following interface configuration command in available:
MPLS_RTR13_SUP720(config-if)#pagp rate ?
fast PAgP packets are transmitted at the fast rate
This command seems to work as the "lacp rate fast" but the difference is that this pagp command is not referenced on the CCO neither in the command reference guides.
Could anyone confirm me that this command is supported or not?
Our customer infrastructure is in pagp and we would prefer to keep this protocol and use the rate fast feature than modifying all etherchannel from pagp to lacp to get advantage of the rate fast feature.
