7. To configure the ratio and priority of an existing pool member
and to display the current SLB pool statistics, use this command
for each pool member, filling in the ipaddress, port, ratio and prio-
ity as needed:
configure slb pool <poolname> member
<ipaddress: port> [ratio <ratio> | priority
<priority>]
8. Enable SLB and configure it for the appropriate VLANs (client
connections enter from the VLAN
inside), using these com-
mands:
enable slb
configure inside slb client
configure server slb server
9. Enable the routing protocol of choice (in this example, OSPF) and
configure it appropriately, using this command:
enable ospf
See Chapter 13, RIP and OSPF for more information.
10. Enable the ESRP protocol on the VLAN
server and configure the
ESRP direct-attached hosts mode to allow the proper failover of
services, using these commands:
enable esrp server
configure esrp port-mode host ports 1-4, 8
The interconnection between the switches is also configured as
a host port.
11. Configure SLB to use the ESRP protocol, using this command:
configure slb esrp server add unit 1
Combined SLB and ESRP failover
You can combine SLB and ESRP to provide a high availability
topology. Use these two commands to map an ESRP configured
VLAN to the SLB failover unit number and to display the current
SLB/ESRP configuration:
configure slb esrp vlan <vlan name> [add | delete]
unit [1 - 16]
show slb esrp
