spanning-tree msti
Configure multiple spanning tree instance cost and priority for an interface.
Syntax
spanning-tree msti instance {cost cost | priority priority}
Parameters
msti instance Enter the keyword msti and the MST instance number. The
range is from zero (0) to 63.
cost cost (OPTIONAL) Enter the keyword cost then the port cost
value. The range is from 1 to 200000. The defaults are:
• 40-Gigabit Ethernet interface = 1400
• 10-Gigabit Ethernet interface = 2000
• Port Channel interface with one 10 Gigabit Ethernet =
2000
• Port Channel with two 10 Gigabit Ethernet = 1800
• Port Channel with two 100 Mbps Ethernet = 180000
priority priority Enter keyword priority then a value in increments of 16 as
the priority. The range is from 0 to 240. The default is
128.
Defaults
• cost = depends on the interface type
• priority = 128

History
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
spanning-tree mstp
Configures a Layer 2 MSTP interface as an edge port with (optionally) a bridge protocol data unit (BPDU)
guard, or enables the root guard or loop guard feature on the interface.
Syntax
spanning-tree mstp {edge-port [bpduguard [shutdown-on-
violation]] | bpdufilter| rootguard}
Parameters
edge-port Enter the keywords edge-port to configure the interface as
a multiple spanning tree edge port.
bpduguard (OPTIONAL) Enter the keyword portfast to enable Portfast
to move the interface into forwarding mode immediately
after the root fails.
Enter the keyword bpduguard to disable the port when it
receives a BPDU.
