Edit Fabric Settings

You can edit certain fabric settings after the fabric configuration. Changes in the fabric settings are displayed in the efa fabric show output. The efa fabric show 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 does not reflect 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 updated codes.

Edit Fabric IP Range Settings

You can edit the following active fabric settings even after the devices are added in fabric:
- --loopback-ip-range
- --p2p-link-range
- --mctlink-ip-range
You can generate increased IP or IP-Pair 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 loopback-ip-range, p2p-link-range, and mctlink-ip-range settings. Ensure that the prefix mask length is lower than the configured prefix mask length value within the same network.

Edit Fabric BFD Settings

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

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

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, MCT port-channel interfaces, and pushes the configuration to the SLX devices.
