4. In SLB virtual server configuration command
mode, configure the virtual server IP address
(VIP) or proceed to the next step and configure a
range of virtual server IP addresses. You must
specify whether the VIP uses TCP or UDP. For
TCP ports you can optionally specify the FTP
service; for UDP ports you can optionally specify
the TFTP service.
virtual ip-address {tcp | udp} port [service
service-name]
5. In SLB virtual server configuration command
mode, if you did not configure a VIP in the
preceding step, configure a range of virtual
server IP addresses. You must specify whether
the VIPs will use TCP or UDP. For TCP ports
you can optionally specify the FTP service; for
UDP ports you can optionally specify TFTP
service.
virtual-range start-address end-address {tcp
| udp} port [service service-name]
6. In SLB virtual server configuration command
mode, optionally configure a client source NAT
pool to source NAT the traffic through the virtual
server with the IP addresses from the NAT pool.
source nat pool pool
7. In SLB virtual server configuration command
mode, enable the virtual server for service
inservice
8. In SLB virtual server configuration command
mode, optionally configure this virtual server to
participate in VRRP state changes. Specify the
VLAN on which the VRRP is configured and the
virtual router ID associated with the routing
interface for this VRRP.
vrrp vlan vlan vrid
9. In SLB virtual server configuration command
mode, optionally restrict access to this virtual
server to configured clients.
client [ip-address network-mask]
10. In SLB virtual server configuration command
mode, optionally configure UDP application
connections to delete the binding when the reply
packet is received. Bindings created by
UDP-one-shot will not result in the installation of
a hardware connection.
udp-one-shot
11. In SLB virtual server configuration command
mode, optionally configure the stickiness type.
sticky type [sip | sip dip-dport]
12. In SLB virtual server configuration command
mode optionally configure the sticky entry
timeout value for this virtual server.
sticky timeout timeperiod
13. In global configuration command mode,
optionally allow specific clients to access the
load balancing real servers in a particular
LSNAT server farm without address translation.
ip slb real-server access client
client-ip-address {ip-prefix | mask}
14. In router command mode, optionally clear sticky
entries or remove bindings.
clear ip slb {sticky
| bindings} {all | id id |
match {sip | *} {sport | *} {dip | *} {dport | *}}
