Redundant Management Network provides fault tolerance for the management path. This is done
using Linux bonding by pairing the physical management port of the chassis with any one
of the physical front panel user ports.
The redundant-management enable command can be used to pair one of
the front panel ports with the conventional Mgmt 0 port
to form a Linux Bonding interface, bond0 at SLX Linux
The Linux bond will be in Active/Standby mode. The Physical Management port is
the primary and active port. The configured front panel port will be in Standby
mode 1 supported by Linux Bonding with
(eth0) is the primary port.
The front panel port allows traffic through it only if
Mgmt 0 is down. Mgmt
0 takes over Active port as soon as it recovers.
If the active primary Mgmt 0 path
experiences failure, SLX OS and TPVM OS can be reached through Standby
Any SLX front panel port can be used at native speed and property for Linux
SLX 9640 and SLX 9150
- Preferred ports are 10G/1G port in 1G mode.
SLX 9640 - Avoid Insight port 0/24.
SLX 9250 - Breakout
mode 4x1G ports are available to support the Mellanox adapter with 1G
transceiver. Because the adapter occupies the whole cage, only the first
member port (:1) can be used as redundant management interface.
8720 has a dual management port. It does not need RME CLI.
No Redundancy Period
Redundancy is not supported if the device is reloaded or in ZTP mode.
After reloading a device, use the
redundant-management enable command or startup config
replay to enable Linux Bonding or redundancy.
Upon factory arrival, across first power cycle, or due to write
erase CLI, ZTP mode is set in with factory default
Breakout mode 1G ports are not supported in
the factory default configuration.
Standby Port Rate Throughput
Since internal path for Standby traffic is Control Plane traffic on PCIe Channel
between ASIC and CPU, its function of internal CPU load is totally unrelated and
independent of front panel physical port limit and capability.
