Note
|
Default value is in the range of 1501-3964.
|
|
Switchpool wide vPC L3 peering VLANs
|
Select the pool of VLANs the Cisco Nexus Fabric Manager will draw from for creating the overlay point-to-point routed links over vPC peer links.
Note
|
Default value is 3965.
|
|
vPC cluster VLAN
|
Enter the VLAN ID used to program SVI interfaces for vPC Layer 3 peer links (underlay).
Note
|
Default value is 3966.
|
|
Default role for unrecognized neighbor devices
|
The default role is used when not enough information is available for the NFM to automatically detect the role of a connect neighbor device.

General Tab > Default profiles
|
Leaf switch
|
Click the drop-down list to choose a leaf switch profile to be applied to all discovered or assigned leaf switches.
|
Spine switch
|
Click the drop-down list to choose a spine switch profile to be applied to all discovered or assigned spine switches.
|
Host facing interface
|
Click the drop-down list to choose a host-facing interface profile to be applied to all host-facing interfaces.
|
Leaf/spine interface
|
Click the drop-down list to choose a switch facing interface profile to be applied to all Leaf/spine interfaces.
|
Border interface
|
Click the drop-down list to choose a border interface profile to be applied to all border interfaces.
|
MORE Tab |
Reserved VLANs
|
Set the pool of VLANs that the Cisco Nexus Fabric Manager must not use. This must be in sync with the set of reserved VLANS defined within NX-OS on the managed switch.
Note
|
Default value is in the range of 3968-4095.
|
|
More Tab > Switchpool default VRF
|
VLAN ID
|
Specify the default VLAN ID reserved for SVI as part of VXLAN routing within a default VRF.
Note
|
Default value is 3967.
|
|
VNID
|
Specify the default VNID reserved for VXLAN routing within the default VRF.
Note
|
Default value is 16777214.
|
|
UNDERLAY Tab |
MAC address
|
Set the MAC address used for all anycast gateways.
Note
|
The MAC address is auto-generated by default.
|
|
BGP router AS number
|
Enter the autonomous system used for BGP service in underlay.
|
BGP Authentication
|
When BGP authentication is enabled, BGP routing updates exchanged between peers are verified and accepted only if authentication is successful. This prevents malicious or incorrect routing information from being introduced into the routing table.
|
BGP authentication key
|
For BGP authentication to be successful, peers must be configured with the same authentication key. The key must be at least 1 character and at most 80 characters.
|
OSPF router instance tag
|
Set the instance number used for OSPF service in the underlay.
Note
|
Default value is 100.
|
|
OSPF authentication
|
When OSPF authentication is enabled, OSPF routing updates exchanged between peers are verified and accepted only if authentication is successful. This prevents malicious or incorrect routing information from being introduced into the routing table.
|
OSPF authentication key
|
For OSPF authentication to be successful, peers must be configured with the same authentication key. The key must be at least 1 character and at most 16 characters.
|
OSPF key ID
|
The OSPF key ID allows the switches to reference multiple passwords. This makes password migration easier and more secure. For example, to migrate from one password to another, configure a password under a different key ID and remove the first key.
|
Underlay MTU
|
Specify the maximum frame size used on underlay interfaces. The system jumbo MTU and overlay interfaces automatically set to this value minus 50.
Note
|
Default value is 9216.
|
|
VNID allocation offset
|
The number to be used as a fixed offset of VLAN IDs for numbering VXLAN VNIDs
Note
|
Default value is 20000.
|
|
UNDERLAY Tab > Underlay pool |
IP address pool
|
Set the IP address subnet used for underlay addressing. This is automatically divided and assigned to underlay interfaces and links. This range must be adequately sized according to the expected fabric size.
Note
|
Default value is 10.0.0.0/8.
|
|
ADVANCED Tab |
Auto-create port channels |
Specifies whether to automatically build port channels out of parallel leaf-spine links. This field has been disabled and cannot be enabled.
|
vPC delay restore |
Enter the vPC delay restore in seconds. Note
|
Default value is 60.
|
|
vPC Auto-recovery reload-delay |
Enter the vPC auto-recovery reload delay in seconds. Note
|
Default value is 300.
|
|
Automatic neighbor assertions |
Specifies whether to automatically create a fault when the neighbor of an interface or port channel changes. This can be helpful for detecting ports that have been cabled incorrectly.
Note
|
This feature is Enabled by default. However, if you plan to move devices around, especially swapping ports for devices discovered through CDP or LLDP, it is recommended to turn this feature off. Otherwise, this feature will generate faults and require remediation actions be taken before a device will connect to the new port that was previously occupied by another discovered device.
