5424 Configuration with iSCSI and failover
I’m setting up a recovery site for our company’s production servers (small company in the same building with recovery site on the opposite side) which will be using 2x power connect 5424 switches, 2x Dell PowerEdge 2950 servers running VMware ESX, and 2 Dell Equal logic PS4000 SANs. I’ve configured the 2x 5424 switches for 2 vlans and a LAG group (vlan 100-Management on ports 1-2, vlan 200-iSCSI with jumbo frames turned on using ports 3-22, LAG on ports 23-24). Since I am new to this, I would like to see if this configuration is correct or if there are any changes that need to be made? The intention is for the LAG to be used for fail over since these switches don’t have the stacking module. Thanks for your help. ///////////////////////////////// 5424 Config ///////////////////////////////// RS_5424-1# RS_5424-1# show run spanning-tree mode rstp interface range ethernet g(3-22) spanning-tree portfast exit interface range ethernet g(1-2) description 'Management' exit interface range ethernet g(3-22) description 'iSCSI' exit interface range ethernet g(3-22) flowcontrol on exit port jumbo-frame interface port-channel 1 switchport mode trunk exit vlan database vlan 100,200 exit interface range ethernet g(1-2) switchport access vlan 100 exit interface port-channel 1 switchport trunk allowed vlan add 100 exit interface port-channel 1 switchport trunk allowed vlan add 200 exit interface vlan 200 name iSCSI exit interface range ethernet g(23-24) channel-group 1 mode on exit interface vlan 100 ip address 192.#.#.# (subnet_mask) exit ip default-gateway 192.#.#.# hostname RS_5424-1 line telnet password xxxxxxxxxxxxxx encrypted exit username admin password xxxxxxxxxxxxx level 15 encrypted clock timezone -5 clock summer-time recurring usa zone utc Default settings: Service tag: ?????

DELL-Daniel C, Thanks for your reply. The LAG group will be connected to another (identical) 5424 iSCSI switch. I have ports 23 & 24 dedicated to the LAG. Do I need to cross the ports when connecting them from one 5424 to the other one, or, do I need to just run from port 23 of one 5424 to port 23 on the other 5424? Thanks again for your help.

With using a LAG, should I be able to plug into any one of the two switches, issue a ping, and get a response from a device that is on the other switch? They are both on the same subnet along with the pc that is issuing the ping. This is the same configuration as mentioned before where I'm using (2) 5424 in a group and use one for failover. I have listed the configuration again for reference. Thanks for the help.
