H3C MSR810 - Encapsulation

208
Field
Description
Link
Physical connection state of the interface:
• UP—The interface is physically up.
• ADM—The interface was shut down manually. You can bring up
the interface by using the undo shutdown command.
• Stby—The interface is a standby interface.
Protocol
Data link layer protocol state:
• UP—The data link layer is up.
• DOWN—The data link layer is down.
• UP(s)—The data link layer protocol state of the interface is up, but
its link is an on-demand link or not present at all.
Main IP Primary IP address of the interface.
Description
Description for the interface configured with command
description
.
The
display interface brief
command displays the first 27 characters
when you do not specify the
description
keyword. It displays the entire
description when you specify the
description
keyword.
Cause
Cause for a down physical link:
• Administratively—The link was shut down by using
the shutdown command. To restore the physical state of the
interface, use the undo shutdown command.
• Not connected—No physical connection exists (probably due to
network cable failures).
encapsulation
Use encapsulation to configure the ATM AAL5 encapsulation type for a PVC or PVC-group.
Use undo encapsulation to restore the default.
Syntax
encapsulation { aal5mux | aal5nlpid | aal5snap }
undo encapsulation
Default
The ATM AAL5 encapsulation type is aal5snap.
Views
PVC view
PVC-group view
Predefined user roles
network-admin
Parameters
aal5mux: Specifies the MUX multiplexing encapsulation type.
aal5nlpid: Specifies the RFC1490 encapsulation type.
aal5snap: Specifies the LLC/SNAP encapsulation type.
Usage guidelines
Different encapsulation types support different mappings:
• aal5snap encapsulation supports IPoA, IPoEoA, PPPoA, and PPPoEoA mappings.
