1 Introduction This document illustrates how to configure Dell™ Networking S4810 and Dell Force10™ S4810 switches for use with EqualLogic™ PS Series storage using Dell best practices. The recommended configuration uses link aggregation groups (LAGs) for inter-switch connections. Optional steps are provided in Section 3 to enable Data Center Bridging (DCB) and for stack configurations. If you are following the Rapid EqualLogic Configuration steps at http://en.community.dell.
1.3 Cabling diagram The cabling diagram shown below represents the Dell recommend method for deploying your servers and EqualLogic arrays.
2 Dell recommended switch configuration These steps show you how to configure two S4810 switches with a Link Aggregation Group (LAG). The switches are interconnected using two of the 40 GbE Quad Small Form-factor Pluggable (QSFP) uplink ports, and the LAG is configured for Dynamic Link Aggregation Control Protocol (LACP). 2.1 Hardware configuration 1. 2. 3. 4. 5. 2.2 Power on the two switches. Connect a serial cable to the serial port of the first switch.
2.4 Configure route for OOB management port (optional) FTOS(conf)#management route X.Y.Z.0 /24 A.B.C.1 Note: X.Y.Z.0 is the network your management system is connecting from and A.B.C.1 is the gateway for the switch. If your management system is on the same subnet as the switch, the previous step may be omitted. The example above assumes a class C subnet mask. 2.
2.9 Configure spanning tree on edge ports FTOS(conf-if-range-te-0/0-47)#spanning-tree rstp edge-port FTOS(conf-if-range-te-0/0-47)#exit FTOS(conf)#protocol spanning-tree rstp FTOS(conf-rstp)#no disable FTOS(conf-rstp)#exit 2.10 Configure port channel for LAG These commands configure the switch interconnect as a LAG. FTOS(conf)#interface Port-channel 1 FTOS(conf-if-po-1)#mtu 12000 FTOS(conf-if-po-1)#switchport FTOS(conf-if-po-1)#no shutdown FTOS(conf-if-po-1)#exit 2.
3 Configure Data Center Bridging (DCB) (Optional) To enable DCB mode on the switch, use the following commands. Note: You must complete the Dell recommended switch configuration steps in Sections 2.1 to 2.12 before configuring the switch for DCB mode. 3.1 Disable 802.3x flowcontrol on SFP+ ports FTOS#configure FTOS(conf)#interface range tengigabitethernet 0/0 - 47 FTOS(conf-if-range-te-0/0-47)#no flowcontrol rx on tx off FTOS(conf-if-range-te-0/0-47)#exit 3.2 Disable 802.
3.5 Configure DCB policies FTOS(conf)#dcb-map profile-name FTOS(conf-dcbmap-profile-name*)#priority-group 0 bandwidth 50 pfc off FTOS(conf-dcbmap-profile-name*)#priority-group 1 bandwidth 50 pfc on Note: The sum of the bandwidth-percentages must be equal to 100. FTOS(conf-dcbmap-profile-name*)#priority-pgid 0 0 0 0 1 0 0 0 FTOS(conf-dcb-profile-name*)#exit 3.
4 Reverting from DCB to non-DCB configuration (Optional) One method to revert from a DCB configured switch to a non-DCB configured switch is to delete the current configuration (startup-config) and follow the steps in Section 2. If deleting the current configuration is not an option, then use the following procedure to unconfigure DCB and enable standard flow control. Note: This is a disruptive operation that requires down time. The arrays will temporarily lose communication with each other.
FTOS#configure FTOS(conf)#no interface vlan vlan-id 4.4 Save configuration FTOS#copy running-config startup-config 4.5 Reload FTOS#reload System configuration has been modified. Save? [yes/no]yes Proceed with reload [confirm yes/no]yes Note: The switch will reboot. 4.6 Verify DCB status FTOS#show dcb Figure 2 4.7 Screen shot of show DCB Configure additional switch Repeat the commands from section 4 to disable DCB on any additional switches.
5 Optional stack configuration Note: If you wish to use a stack configuration instead of LAG, follow the instructions below instead of Section 2. One advantage of stacked switches is that they can be managed as a single switch; however firmware updates will update all members of the stack simultaneously and therefore should only be done during planned downtime. 5.
Note: The switch will reboot. 5.4 Configure stack on the second switch FTOS>enable FTOS#stack-unit 0 renumber 1 Note: The switch will reboot. FTOS#config FTOS(conf)#stack-unit 1 priority 1 FTOS(conf)#stack-unit 1 stack-group 12 FTOS(conf)#stack-unit 1 stack-group 13 FTOS(conf)#exit FTOS#copy running-config startup-config FTOS#reload 5.
5.8 Configure login credentials FTOS(conf)#username admin privilege 15 password 0 yourpassword FTOS(conf)#enable password level 15 0 yourpassword 5.
