In interface configuration mode, configure an IP map to use Cisco
encapsulation and TCP/IP header compression:
frame-relay map ip
ip-address dlci
[broadcast] cisco tcp headercompression
{active | passive}
The default encapsulation is cisco.
Note:
An interface that is configured to support TCP/IP header
compression cannot also support priority queuing or
custom queuing.
Configure an Interface for TCP/IP Header Compression
You can configure the interface with active or passive TCP/IP header
compression. Active compression, the default, subjects all outgoing
TCP/IP packets to header compression. Passive compression subjects
an outgoing packet to header compression only if the packet had a
compressed TCP/IP header when it was received on that interface.
In interface configuration mode, apply TCP/IP header compression to
an interface:
1.
Configure Cisco encapsulation on the interface.
encapsulation frame-relay
2.
Enable TCP/IP header compression on the interface.
frame-relay ip tcp header-compression
[passive]
Note:
If an interface configured with Cisco encapsulation is
later configured with IETF encapsulation, all TCP/IP
header compression characteristics are lost. To appl
TCP/IP header compression over an interface configured
with IETF encapsulation, you must configure individual
IP maps, as described in the section
