What is zyMstpInstanceBridgePriority?

Sets this switch's bridge priority (0-61440, in steps of 4096, default 32768) for a specific spanning tree instance; a lower value makes the switch more likely to be elected root bridge for that instance.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.53.1.5.1.2
snmpwalk -v2c -c public <target> ZYXEL-MSTP-MIB::zyMstpInstanceBridgePriority

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.53.1.5.1.2.1
snmpget -v2c -c public <target> ZYXEL-MSTP-MIB::zyMstpInstanceBridgePriority.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.890.1.15.3.53.1.5.1.2.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> zyMstpInstanceBridgePriority.1
