I want to stress all ports on a SN3700 switch with iPerf. I want to force the traffic to go through each port, so port 1 to port 2, port 2 to port 3, port 3 to port 4, etc.
The switch is running Cumulus Linux 5.6. I have a support unit, Unit 1, connected to port 1, and a support unit, Unit 2, connected to port 32. There are direct-attach cables connecting all other ports, so port 2 is connected to port 3, port 4 to port 5, etc. I am running the iPerf client on Unit 1 (connected to port 1) and the iPerf server on Unit 2 (connected to port 32).
I'm not sure I have the VLANs configured correctly. I have swp1 and swp2 in VLAN5, swp3 and swp4 in VLAN6, etc.
I've done this on a SN3700 with Onyx OS, and on a Ruckus switch with FastIron, but I don't believe I have the correct configuration for this SN3700 running Cumulus Linux 5.6.
Example contents of the /etc/network/interfaces file:
auto swp1
iface swp1
auto swp2
iface swp2
. . .
auto swp32
iface swp32
auto br_vlan5
iface br_vlan5
bridge-ports swp1 swp2
bridge-vlan-aware no
bridge_stp off
auto br_vlan6
iface br_vlan6
bridge-ports swp3 swp4
bridge-vlan-aware no
bridge_stp off
. . .
auto br_vlan20
iface br_vlan20
bridge-ports swp31 swp32
bridge-vlan-aware no
bridge_stp off
I expected to be able to pass traffic from Unit 1 through each switch port sequentially (Unit 1 in to port 1, (internally "routed") to port 2, out to port 3, (internally "routed") to port 4, ..., out from port 32 to Unit 2). I can't even ping Unit 2 from Unit 1.
What am I missing? TIA!
