Description (partial)

None

Symptom:
Enabling passive header compression on interface where active header compression is enabled doesn't
get reflect in show running configuration of interface. Though its get updated in show frame-relay
map command output.

Also, the header compression is not working as desired after this configuration. Ideally if both
side are configured for Passive, compression should not happen. In this case compression is
happening though "sh frame relay map" command shows both interfaces are configured as passive.


 
Conditions:

Following command:
frame-relay map ip <ip> <dlci> compress passive
given after 
frame-relay map ip <ip> <dlci> compress active
for same ip and dlci values does not take effect.
