Parameters
instance-id-list: Specifies a space-separated list of up to 10 MSTI items. Each item specifies an MSTI or a range of MSTIs in the form of instance-id1 to instance-id2. The value for instance-id2 must be greater than or equal to the value for instance-id1. The value range for the instance-id argument is 0 to 4094. The value 0 indicates CIST. You can use the display stp region-configuration command to display the VLAN-to-instance mappings. In PVST mode, the system automatically maps VLANs to MSTIs.
Usage guidelines
If you do not specify the reference-instance instance-id-list option, the undo protected-vlan command deletes all mappings between MSTIs and VLANs in the ERPS instance. The protected VLANs change if the mappings between the MSTIs and VLANs change.

Predefined user roles
network-admin
Parameters
guard-value: Specifies the guard timer in the range of 0 to 2000 milliseconds and in step of 10.
Usage guidelines
The guard timer starts when the link recovers. The system processes only the flush packets before the guard timer expires. The guard timer prevents SF messages from impacting the network.
Examples
# Set the guard timer to 30 milliseconds for instance 1 of ERPS ring 1.
<Sysname> system-view
[Sysname] erps ring 1

Predefined user roles
network-admin
Parameters
hold-off-value: Specifies the hold-off timer in the range of 0 to 10000 milliseconds and in step of 100.
Usage guidelines
The hold-off timer starts when the port detects a link fault. If the link fault persists when the hold-off timer expires, the port reports the link fault. The hold-off timer delays the fault report time and might impact the link recovery performance.
Examples
# Set the hold-off timer to 300 milliseconds for instance 1 of ERPS ring 1.
<Sysname> system-view
[Sysname] erps ring 1
[Sysname-erps-ring1] instance 1
