Configuring Data Compression Services
2-8 114061 Rev. A
Compression Features for Specific Protocols
Bay Networks data compression services vary in some details according to the
WAN protocols that you configure. Read the following sections to learn about
how our implementation of data compression applies to Frame Relay, PPP, and
X.25 services.
Frame Relay Services
You can use software- or hardware-based data compression with Frame Relay.
You can use compression with some VCs, and not with others, as you choose,
both for regular Frame Relay VCs, and for those you configure in hybrid mode.
You can also use compression with dial backup.
You must enable compression on both sides of a Frame Relay link. If you enable
data compression on only one side of the link, data transmission occurs, but in
uncompressed form.
Frame Relay Hybrid Access
Hybrid access enables you to combine bridging and routing over a single Frame
Relay interface.
When you enable data compression for Frame Relay on a hybrid circuit, both the
bridged and the routed traffic over that circuit are compressed. Note that
compression applies only to the hybrid PVC, and not to the other PVCs from the
main circuit, unless you have also enabled compression for those interfaces.
Conversely, if you enable data compression for other PVCs, but not on a PVC you
have configured for hybrid mode, the hybrid circuit does not use compression.
Frame Relay Dial Backup
Frame Relay enables you to configure a dial backup feature. If a primary Frame
Relay circuit fails and you have enabled dial backup, the router automatically
establishes a backup circuit. The backup circuit can be PPP or Frame Relay for a
Frame Relay service record with only one PVC. The backup circuit is Frame
Relay for a Frame Relay service record with two or more PVCs.
