M Commands
This chapter describes the Cisco NX-OS FabricPath commands that begin with M.
maximum-paths (FabricPath)
To configure the maximum number of paths per destination, use the maximum-paths command. To return to the default setting, use the no form of this command.
maximum-paths paths
no maximum-paths paths
Syntax Description
paths |
Maximum number of paths per destination. The range is from 1 to 16. |
Defaults
The default value is 16.
Command Modes
FabricPath IS-IS configuration mode
Command History

|
|
|---|---|
5.1(3)N1(1) |
This command was introduced. |
Usage Guidelines
This command requires an Enhanced Layer 2 license.
Examples
This example shows how to configure the maximum number of paths per destination:
switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# fabricpath domain default
switch(config-fabricpath-isis)# topology 1
switch(config-fabricpath-isis-topo)# maximum-paths 1
switch(config-fabricpath-isis-topo)#

show fabricpath isis |
Displays FabricPath Layer 2 IS-IS. |
max-lsp-lifetime (FabricPath)
To configure a lifetime for a maximum link-state packet (LSP), use the max-lsp-lifetime command. To return to the default setting, use the no form of this command.
max-lsp-lifetime value
no max-lsp-lifetime value
Syntax Description
value |
Maximum LSP lifetime in seconds. The range is from 1 to 65535. |
Command Default
1200 seconds
Command Modes
FabricPath IS-IS configuration mode
Command History
|
|
|
|---|---|
5.1(3)N1(1) |
This command was introduced. |
Usage Guidelines
The maximum LSP lifetime must be greater than the LSP refresh interval.
This command requires an Enhanced Layer 2 license.
Examples
This example shows how to set the maximum time that the link-state packets persists to 11,000 seconds:
switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# fabricpath domain default
switch(config-fabricpath-isis)# max-lsp-lifetime 1300
switch(config-fabricpath-isis)#

mode (FabricPath)
To configure VLANs as FabricPath VLANs for FabricPath forwarding, use the mode command. To remove the FabricPath VLANs, use the no form of this command.
mode {ce | fabricpath}
no mode {ce | fabricpath}
Syntax Description
ce |
Enables the VLAN as a Classical IEEE 802.1Q Ethernet (CE) VLAN. This is the default VLAN mode. |
fabricpath |
Enables the VLAN as a FabricPath VLAN. |
Command Default
The default VLAN mode is ce.
Command Modes
VLAN configuration mode
Command History
|
|
|
|---|---|
5.1(3)N1(1) |
This command was introduced. |
Usage Guidelines
Ensure that you have enabled the FabricPath feature set.
Note 
You must have already created the VLANs before you can set the VLAN mode using FabricPath.
You designate those VLANs that you want to carry FabricPath traffic on the network by configuring them as FabricPath VLANs. By default, all FabricPath VLANs and FabricPath interfaces are added to the default FabricPath topology.
All FabricPath VLANs use conversational learning only if the switch virtual interface (SVI) is not enabled on the VLANs; otherwise, FabricPath VLANs use traditional learning.
Only FabricPath VLANs support conversational learning. CE VLANs support only traditional learning.
This command requires an Enhanced Layer 2 license.
Examples
This example shows how to configure a VLAN as a FabricPath VLAN:
switch# configure terminal
switch(config)# vlan 5
switch(config-vlan)# mode fabricpath
switch(config-vlan)#
This example shows how to remove a FabricPath VLAN:
switch# configure terminal
switch(config)# vlan 5
switch(config-vlan)# no mode fabricpath
switch(config-vlan)#
