Configuring the Catena Solution
SUMMARY STEPS
1. configure terminal
2. catena device-group device-group-name
3. node {ip ipv4-address | IPv6 ipv6-address }
4. probe probe-id [control status] [host host-name] [frequency frequency-number | timeout timeout |
retry-down-count down-count | retry-up-count up-count | ip ipv4-address]
5. (Optional) vrf vrf-name
DETAILED STEPS
Command or Action
Step 1
configure terminal
Example:
switch# configure terminal
switch(config)#
Step 2
catena device-group device-group-name
Example:
switch(config)# catena device-group s-dg-1
Step 3
node {ip ipv4-address | IPv6 ipv6-address }
Example:
switch(config-device-group)# node ip
1.1.1.1
switch(config-device-group)# node ip
2.2.2.2
switch(config-device-group)# node ip
3.3.3.3
Example:
switch(config-device-group)# node ipv6
210::10:10:11
switch(config-device-group)# node ipv6
210::10:10:12
Step 4
probe probe-id [control status] [host host-name]
[frequency frequency-number | timeout timeout |
retry-down-count down-count | retry-up-count
up-count | ip ipv4-address]
Example:
switch(config-device-group)# probe icmp
Purpose
Enters global configuration mode.
Creates a device group and enters the device group configuration mode.
Configures a list of node IP addresses. These are the IP addresses of
your appliances. Traffic is redirected to the appliances that can perform
load balancing. These devices must be in active mode. In the example,
node ip 1.1.1.1, node ip 2.2.2.2, and node ip 3.3.3.3 are the IP addresses
of the appliances.
Configure the device group probe.
You can specify an Internet Control Message Protocol (ICMP),
Transmission Control Protocol (TCP), User Datagram Protocol (UDP),
or Domain Name System (DNS) probe for the catena instance.
The following describe some of the keyword-argument pairs:
• control status—Specifies the control protocol status.
• frequency frequency-number—Specifies the time interval, in
seconds, between successive probes sent to the node.
• timeout timeout—Specifies the number of seconds to wait for
the probe's response.
