Edit Fabric Settings

You can edit certain fabric settings after the fabric configuration.

Changes made in the fabric settings are displayed in the efa fabric show command output. The efa fabric show command output marks the changed settings as Updated Fabric Settings and corresponding modification codes are displayed.

efa fabric show output:
...
Updated Fabric Settings: BGP-LL
FABRIC SETTING:
BGPLL - BGP Dynamic Peer Listen Limit, BGP-MD5 - BGP MD5 Password , BFD-RX - Bfd Rx Timer, BFD-TX - Bfd Tx Timer, BFD-MULTIPLIER - Bfd Timer,BFD-ENABLE - Enable Bfd, BGP-MULTIHOP - BGP ebgp multihop, P2PLR - Point-to-Point Link Range, MCTLR - MCT Link Range, LOIP - Loopback IP Range..

Changes are not reflected in app-state, drc-drift, and drc-reconcile show outputs.
Changes are pushed into SLX only after you run the efa fabric configure command.
After successful execution of the efa fabric configure command, the efa fabric show command clears the fabric status and fabric settings.

Edit Fabric IP Range Settings

You can edit the following active fabric IP range settings even after the devices are added in fabric:
- --loopback-ip-range
- --p2p-link-range
- --mctlink-ip-range
You can generate increased IP addresses or IP-Pairs and update them in the available IP-Pool. There are no updates to the used IP-pair. For example,
- Old IP range: 10.10.10.1/24
- New IP range: 10.10.10.1/23
- Increased IP range: 10.10.10.1/23 - 10.10.10.1/24
The increased IP addresses are available for use when new devices are added into the fabric.

You can edit lloopback-ip-range, p2p-link-range, and mctlink-ip-range settings. Within the same network, ensure that the prefix mask length is lower than the configured prefix mask length.

‘efa fabric show‘ output sample:

Fabric Name: fs, Fabric Description: , Fabric Type: non-clos, Fabric Status: settings-updated
Updated Fabric Settings: MCTLR,P2PLR,LOIP 
FABRIC SETTING:
BGPLL - BGP Dynamic Peer Listen Limit, BGP-MD5 - BGP MD5 Password , BFD-RX - Bfd Rx Timer, BFD-TX - Bfd Tx Timer, BFD-MULTIPLIER - Bfd Timer,BFD-ENABLE - Enable Bfd, BGP-MULTIHOP - BGP ebgp multihop, P2PLR - Point-to-Point Link Range, MCTLR - MCT Link Range, LOIP - Loopback IP Range

Edit Fabric BFD Settings

You can edit the following active fabric BFD settings even after the devices are added in fabric:

--bfd-enable <yes|no>
--bfd-tx <val>
---bfd-rx <val>
--bfd-multiplier<val>

The following is an example output of the efa fabric show command:

Fabric Name: fs, Fabric Description: , Fabric Stage: 3, Fabric Type: clos, Fabric Status: settings-updated

Updated Fabric Settings: BFD-ENABLE,BFD-TX,BFD-RX,BFD-MULTIPLIER

FABRIC SETTING:
BGPLL - BGP Dynamic Peer Listen Limit, BGP-MD5 - BGP MD5 Password, BFD-RX - Bfd Rx Timer, BFD-TX - Bfd Tx Timer, BFD-MULTIPLIER - Bfd Timer,BFD-ENABLE - Enable Bfd, BGP-MULTIHOP - BGP ebgp multihop, P2PLR - Point-to-Point Link Range, MCTLR - MCT Link Range, LOIP - Loopback IP Range

The efa fabric configure command generates BFD recipe for router BGP, interface links, and MCT port-channel interfaces, and then pushes the configuration to the SLX devices.
