Force10 S4820T Config issues
2 Force10 S4820T config problems
What I'm trying to do is:
a) Stack them for auto failover (their cross connected A52->B60 and B52->A60)
b) vlan 1 ports 0-23 on each for lan (untagged)
c) vlan 2 ports 24-47 on each for iscsi (untagged)
d) Ports A23 & B23 to be setup for LAG and connect to a pair of N3000 (LAN) switches (until all servers moved to the Force10's 0-23)
e) Ports A47 & B47 to be setup for LAG and connect to a pair of N3000 (iSCSI) switches (until all data lines moved to the Force10's 24-47)
So I thought the failover would be fairly straight fwd but...
a) the lan connection on switch B port 23 & iscsi port 47 not linked (no lights) neither on the N3000's end (Switch A is fine)
b) pulled the power from switch A and I'm dead in the water, my laptop is plugged in to switch B with no link
Show VLAN: all showing active for both
Show Redundancy: Unit 1 = Mgmt, Unit 2 = Standby
Only the Pwr & B52/60 have any lights, the rest stay off and dead
TIA.. Jim

If you reconnect to switch A does it work again? The roles sound correct for the stack, but it should just failover and work. Can you connect with serial and see what switch B shows after switch A is failed?
Ok, console port connected to standby, pulled pwr from master, standy sees failed heartbeat and takes control, still no live ports with laptop connected to standby, pwr up master and it takes control back, so looks like failover is working, just no ports on standby, all the ports are config'd exactly the same as master
as in: oh
now i feel like , range 2/0 - 47 were at 'shutdown' doh!
working now!

Hi Jim, Nothing special, it should work when you set up the port channel.
Still not put into production yet, trying to stay on top of day2day stuff that never seems to give me a break lol
the next bit i have to do is setting up LACP for:
a) LACP (0/23,1/23) uplink to a PC5324 (19/20), do i need to do anything on the 5324?
b) LACP 0/0,0/1,1/0,1/1 for the 1st server (Teamed NICs)
Still trying to read up on it

Which instructions did you use? I don’t see a need to specify active https://dell.to/2EVfZ0q
So this is what I came up with after a bit of reading:
Force10(config)#interface port-channel 1
Force10(config)#no shutdown
Force10(conf-if-po-1)#description "lines to adc01"
Force10(conf-if-po-1)#channel-member 0/0
Force10(conf-if-po-1)#channel-member 0/1
Force10(conf-if-po-1)#channel-member 1/0
Force10(conf-if-po-1)#channel-member 1/1
...
Force10(conf)#interface Gigabitethernet 0/0
Force10(conf-if-gi-0/0)#no shutdown
Force10(conf-if-gi-0/0)#port-channel-protocol LACP
Force10(conf-if-gi-0/0)#port-channel 1 mode active
...
Force10(conf)#interface Gigabitethernet 0/1
Force10(conf-if-gi-0/1)#no shutdown
Force10(conf-if-gi-0/1)#port-channel-protocol LACP
Force10(conf-if-gi-0/1)#port-channel 1 mode active
...
Force10(conf)#interface Gigabitethernet 1/0
Force10(conf-if-gi-1/0)#no shutdown
Force10(conf-if-gi-1/0)#port-channel-protocol LACP
Force10(conf-if-gi-1/0)#port-channel 1 mode active
...
Force10(conf)#interface Gigabitethernet 1/1
Force10(conf-if-gi-1/1)#no shutdown
Force10(conf-if-gi-1/1)#port-channel-protocol LACP
Force10(conf-if-gi-1/1)#port-channel 1 mode activeNot sure about this active/passive, i went with all active but I could be wrong and it could be 1 active and 1 passive per switch.
Anyways did I read correctly?

Hi Jim,
What OS version are you running on the switches? It sounds like spanning-tree is treating it as a loop and putting the ports that don’t work in blocking mode.
