fabricpath multicast load-balance
To enable control of two virtual port channel (vPC) peers to be partial designated forwarders when both vPC path are up, use the fabricpath multicast load-balanc e command. To return to the default setting, use the no form of this command.
fabricpath multicast load-balance
no fabricpath multicast load-balance
Syntax Description
Defaults
Command Modes
Command History
|
|
|
|---|---|
Usage Guidelines
When the control is enabled, each peer can be the designated forwarder for multi destination southbound packets for a disjoint set of forwarding tags (FTAGs). The designated forwarder is negotiated on a per vPC basis.
There are three designated forwarder states for a vPC port:
- All—If the local vPC path is up and the peer vPC is not configured or is down, the local switch is the designated forwarder for all Result Bundle Hashes (RBHs) or FTAGS for that vPC.
- Partial—If the vPC path is up on both sides, each peer is the designated forwarder for half the RBHs or FTAGs. In the case of FTAGs, the vPC port allows the active FTAGs on that peer.
- None—If the local vPC leg is down or is not configured, the local switch does not forward any multi destination packets to this vPC path.
This command requires an enhanced Layer 2 license.
Note The fabric path multicast load balancing status (all, partial, or none) can be seen under the vPC+ attributes of the show vpc brief command.
The fabricpath multicast load-balance command is required for configuring vPC+ with Fabric Extender (FEX) ports.
Follow these guidelines when using the fabricpath multicast load-balance command:
- The command flaps peer links and vPCs and leads to traffic loss.
- If the command is not configured on both sides, there will be a Type1 inconsistency on each vPC.
- Remove the Fabric Path multicast load-balance configuration before attempting a nondisruptive software downgrade (ISSD) to an image that does not support this configuration.
Note Only an F2 Series module supports multicast load-balancing. On an F1 Series module, the configuration is supported, but load-balancing does not occur.

fabricpath timers
To configure FabricPath timers, use the fabricpath timers command.

Syntax Description
Defaults
Command Modes
Command History
|
|
|
|---|---|
Added linkup-delay always keyword to the syntax description. |
|
Usage Guidelines
If conflicts are not resolved for user-configured switch ID, warnings are displayed. To avoid incorrect traffic forwarding, keep the delay large enough around 60 seconds for IS-IS to gather all neighbor information while changing the topology. This delay allows the timely detection of conflicts. The links are held down until the conflict is resolved by user intervention or on the expiry of the LSP of the conflicting Switch ID.
Examples
This example shows how to configure the delay for a new switch ID to be propagated throughout the network before that value becomes available and permanent:
This example shows how to configure the link bringup delay to detect conflicts in the switch ID. If the system finds a conflict, the system takes some time to resolve the conflict and to bring FabricPath to an operational state.
This example shows how to configure the delay for propagating a transitioned value in the network; during this period, all old and new switch ID values exist in the network. This transition lasts only until the link comes up and the system checks to see if the network has two identical switch IDs.

Usage Guidelines
You cannot view or access any FabricPath commands until you enable FabricPath on the device.
Note You must install the FabricPath feature set before you enable FabricPath on the switch. See the Configuring Feature Set for FabricPath document for more information about feature sets. Also, you must enable the FabricPath feature set on the default virtual device context (VDC), as well as separately on any other VDCs that are running FabricPath.
Examples

force gateway-down
To enforce an HSRP anycast bundle to remain the down state even if one invalid VLAN is configured for the bundle, use the force gateway-down command. The bundle will come up only when all configured VLANs are valid. This mode favors loss of traffic.
To return to the default setting, use the no form of this command. In this case, the bundle will come up even if one valid VLAN configuration exits. This mode favors loss of anycast gateway.
Note A VLAN is considered to be invalid if it is not completely configured. For example, if the VLAN or SVI is not configured, if HSRP groups are not configured, if configured HSRP groups have incomplete VIP configurations or incorrect HSRP versions, if the VLAN or SVI is in SHUT state, and if the VLAN is not in FP mode.

hardware fabricpath mac-learning
To enable Fabric Path MAC address learning on F2 Series module port groups, use the hardware fabricpath mac-learning command. To disable this feature, use the no form of this command.
hardware fabricpath mac-learning module module-number [ port-group list ]
no hardware fabricpath mac-learning module module-number [ port-group list ]
Syntax Description
List of static port range from 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, 21 to 24, 25 to 28, 29 to 32, 33 to 36, 37 to 40, 41 to 44, and 45 to 48. |
Defaults
Command Modes
Command History
|
|
|
|---|---|
Usage Guidelines
Note Use this command only for F2 Series modules or port groups that have Fabric Path core ports only (or unused/shutdown ports), not customer edge ports or any other type of port.
After you use this command, FabricPath core ports on the specified modules and port groups no longer learn any MAC addresses in the VLANs that do not have switched virtual interfaces (SVIs). This command does not affect forwarding behavior (Fabric Path core ports that do not use the MAC address table to perform forwarding).
For VLANs with SVIs configured (even on port-groups where the CLI is applied), and for port groups that this CLI has not been applied to, the F2 Series module still learns MAC addresses.
Examples
This example shows how to disable hardware FabricPath MAC learning on F2 Series module port-groups regardless of the VDC membership:

Syntax Description

|
|
|
|---|---|
Usage Guidelines
This command allows support for more than 244 vPC+ port channels when configured on both vPC+ peer switches. To enable this command, first enter the fabricpath multicast load-balance command.
Follow these guidelines when using the no port-channel limit command:
- Entering this command could cause the peer link and VPC to go up and down, which could lead to traffic losses.
- Only F2 Series modules support this configuration. It can not be configured on VDCs that do not have an F2 Series module.
- The command changes FabricPath MAC addresses that are used by vPC+ port channels. It leads to some transient flooding until the MAC addresses are learned again.
- An in-service software upgrade (ISSU) and an in-service software downgrade (ISSD) are not supported in this release.
- Remove the no port-channel limit configuration before attempting an ISSD to an image that does not support this configuration. To revert to an earlier configuration, the maximum number of vPCs that you can use is 244
- To unconfigure the FabricPath multicast load-balance configuration, you must first remove the no port-channel limit configuration.
The fabricpath multicast load-balance command must be entered before the no port-channel limit command:
- Only VDCs that have an F2 Series module can support more than 244 vPC+ port channels.
- Support for more than 244 vPC+ port channels (per vPC+ domain) is enabled with the no port-channel limit command.
This command requires an Enhanced Layer 2 license.
Note The no port-channel limit command is not applicable with a Fabric Extender (FEX). A FEX can support more than 244 vPC+ port channels.
