service-policy is removed when changing encapsulation type

[gchabannas]

Hello,

one of my customer encounters a problem with a 7606 in version c6sup22-jk2sv-mz.121-26.E4.bin.

When he changes the encapsulation ( ppp to hdlc or hdlc to ppp ) on his serial interface the service-policy configuration is removed.

Exemple :

xxxx02#sh run int ser 2/1/1

Building configuration...

Current configuration : 223 bytes

!

interface Serial2/1/1

description PAR-DRS_LON_FT

ip address X.X.7.1 255.255.255.252

encapsulation ppp

load-interval 30

dsu bandwidth 44210

framing c-bit

cablelength 10

service-policy output London_policy

end

xxxx02#

xxxx02#conf t

Enter configuration commands, one per line. End with CNTL/Z.

xxxx02(config)#int ser 2/1/1

xxxx02(config-if)#no encapsulation ppp

xxxx02(config-if)#

xxxx02#

xxxx02#sh run int ser 2/1/1

Building configuration...

Current configuration : 167 bytes

!

interface Serial2/1/1

description PAR-DRS_LON_FT

ip address X.X.7.1 255.255.255.252

load-interval 30

dsu bandwidth 44210

framing c-bit

cablelength 10

end

xxxx02#

I didn't find any bug about this.

So , can you tel me if it's normal or not ?

Thanks in advance

Hi Gregory,

I beleive that is quite normal. Changing encapsulation type on an interface is a major re-configuration and you have to accept such behaviour.

Hope that helps - pls rate the post if it does.
