The parameters of VLAN protection are described below.
Table 1 lists the parameters involved in the configuration of VLAN SNCP protection.
Field |
Value |
Description |
|---|---|---|
Service Type |
EPL |
This parameter cannot be edited. |
Service Direction |
Unidirectional, Bidirectional |
Sets the direction of the service. |
Source Port |
For example: PORT4 |
The source port of a VLAN SNCP service. Currently, PORT and VCTRUNK types are supported. |
Sink Port |
For example: VCTRUNK1 |
The sink port of a VLAN SNCP service. Currently, PORT and VCTRUNK types are supported. |
Sink C-VLAN |
For example: 1 |
The VLAN ID of the sink port. Source C-VLAN should be the same as Sink C-VLAN. |
Current Status |
Normal State Lockout State Forced (from Working to Protection) Switching State Forced (from Protection to Working) Switching State Manual (from Working to Protection) Switching State Manual (from Protection to Working) Switching State Automatic Switching State, WTR State SF Switching Unknown |
Displays the switching status of a service. |
Revertive Mode |
Non-Revertive, Revertive Default: Revertive |
Sets whether to switch the services back to the working channel from the protection channel after the working channel resumes normal operation. If Revertive is configured, the services are switched back to the working channel; If Non-Revertive is configured, the services are not switched back to the working channel. Non-Revertive is recommended. |
| WTR Time (s) | 6 to 720 Default: 6 |
Sets the WTR time. It refers to the period between the point that the working channel is normal and the point that services are switched back to the working channel. The Revertive Mode is valid only when the value is Revertive. |
Delay Time (100ms) |
0-100 Default value: 0 |
Sets the amount of time that elapses from the moment that the system detects a signal degrade to the moment that service switching takes place. Set this parameter to avoid repeat switching when services are unstable. The switching delay time is expressed in 100 milliseconds. For example, if you enter 5, the delay time is 500 milliseconds. Sets the delay time. To avoid the repeated switching when the service status is not stable, generally the delay time needs to be set. Especially in the network of multi-protection cascading, to avoid that the switching occurs to downstream protections at the same time, the delay time needs to be set for downstream protections. |
Current Working Link |
Working Link, Protection Link |
Displays the link where services reside. |
Link Status |
Normal, SF |
Displays the working status of the link where services reside. |
OAM Enable |
Enabled, Disabled |
Enables or disables the OAM function. When the L4G and TBE boards are configured with dual fed services, the OAM function at the source end must be enabled. (When creating the VLAN SNCP protection on the TBE board, you can choose not to enable the OAM function because a large amount of traffic may be transmitted) |
