HPE FlexNetwork MSR Series Comware 5 Layer 2 - Wan Access Configuration Guide

290
• When you configure transparent bridging over X.25, you must configure X.25 on the interface
as the link layer protocol for interface encapsulation and configure the operating mode and
datagram format of the interface. When establishing transparent bridging over X.25, you must
configure mappings between bridge addresses and X.25 addresses defined in X.121.
• When you configure transparent bridging HDLC, you must configure HDLC as the link layer
protocol for interface encapsulation.
• When you configure inter-VLAN transparent bridging, you must configure the encapsulation
format of the Ethernet subinterfaces and the VLAN IDs. When establishing inter-VLAN
transparent bridging, you must add the configured Ethernet subinterfaces into a bridge set.
Configuration procedure
To configure basic bridging functionalities:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enable bridging.
bridge enable
Disabled by default.
3. Enable a bridge set.
bridge
bridge-set
enable
No bridge set is enabled by
default.
4. Enter interface view.
interface
interface-type
interface-number
N/A
5. Add the current interface into
a bridge set.
bridge-set
bridge-set
An interface is not in any bridge
set by default.
6. Configure an FR-to-bridging
mapping.
fr map bridge
dlci
broadcast
Optional.
This step configures transparent
bridging over FR.
7. Configure an X.25 to
bridging mapping.
x25 map bridge x121-address
x.121-address
broadcast
Optional.
This step configures transparent
bridging over X.25.
8. Enable bridged traffic over a
PVC.
interface atm
{ interface-number
| interface-number.subnumber }
Optional.
This step configures transparent
bridging over ATM.
If you configure both the
map
bridge virtual-ethernet
and
map
bridge-group
commands, only
the
map bridge virtual-ethernet
takes effect.
pvc
{ pvc-name [ vpi/vci ] |
vpi/vci }
map bridge-group broadcast
For more information about ATM configuration, see "Configuring ATM."
Configuring bridge table entries
A bridge dynamically creates and maintains a bridge table based on the correlations between the
MAC addresses it has learned and the interfaces. The administrator, however, can manually
configure some bridge table entries, which will never get aged out.
The aging time of a dynamic bridge table entry refers to the lifetime of the entry before it is deleted
from the table. When the aging timer of a dynamic table entry expires, the system deletes the entry
from the table.
To configure a bridge table:
