2 - Front panel SFP+, labeled ETH4 (BCM port xe1)
3 - Front panel SFP+, labeled ETH5 (BCM port xe2)
4 - Front panel SFP+, labeled ETH6 (BCM port xe3)
5 - Front panel SFP+, labeled ETH7 (BCM port xe4)
6 - CPU 1 (linux bmc interface) (BCM port xe5)
7 - BMC controller (1Gb) (BCM port xe6)
8 - CPU 2 (linux bmc interface) (BCM port xe7) [dual CPU model only]
This switch is initialized when the Linux kernel comes up on CPU 1. The default
configuration defines a single VLAN (ID 1) and all eight ports are included in this VLAN. In
this configuration there is no switch management and all broadcast packets are routed to
all ports.
Depending on the customer's network topology, the switch should be reconfigured
appropriately.
This release includes the capability to initialize the BCM switch with user-specific
commands and have these commands automatically applied whenever the board is
booted. This configuration step also happens when the
bcm service is restarted.
To use this feature, add the desired BCM commands to the file
/opt/bladeservices/tools/bcm/rc_user.soc
.
The Broadcom switch is configurable from Linux/BBS using the Broadcom utility
bcm.user.proxy
. To execute, type:
bcm.user.proxy
followed by two
<CR>
. The second
<CR>
is needed to see the
BCM.0>
prompt. To exit the utility, type:
exit <CR>
.
Once in the utility both general and specific help is available. For example:
BCM.0> help
BCM.0> help PortStat
Notice in the help output that certain characters are capitalized in the command names.
The capital letters represent the minimum letters necessary (or shortcut) to issue the
command. For example to call the
PortStat
command, the shortcut would be
ps.
In this default configuration broadcast storms can easily be created if multiple front
panel connections are made.
