critical-resource
   
      Profile Config Commands
Enables monitoring of resources
            critical to the health of the service platform, wireless controller,
            or access point managed network. These critical resources are
            identified by their configured IP addresses. When enabled, the
            system monitors these devices regularly and logs their status. Use
            this command to create a CRM (critical resource
               monitoring) policy.
A critical resource can be a gateway, AAA server, WAN interface, any hardware, or a service on which the stability of the network depends. Monitoring these resources is therefore essential. When enabled, this feature pings critical resources regularly to ascertain their status. If there is a connectivity issue, an event is generated stating a critical resource is unavailable. By default, there is no enabled critical resource policy and one needs to be created and implemented.
Critical resources can be monitored directly through the interfaces on which they are discovered. For example, a critical resource on the same subnet as an AP8132 access point can be monitored by its IP address. However, a critical resource located on a VLAN must continue to be monitored on that VLAN.
Critical resource monitoring can be enabled on service platforms, wireless controllers, and access points through their respective device profiles.

                                    server). Specify the IP address in the A.B.C.D format. You can

                                    from 1 - 4094. Alternately, use a vlan-alias to identify the
                                    VLAN. If using a vlan-alias, ensure that the alias is existing
                                    and configured. | 
                  
                     | dns
                        <IP/HOST-ALIAS-NAME> | The following
                        parameters are recursive and common to the ‘all‘, ‘cluster-master‘, and
                        ‘rf-domain-manager‘ keywords: 
                           dns – Configures DNS as
                              the mode of monitoring critical resources. When configured, DNS
                              message flows are used instead of ICMP or ARP packets to confirm
                              critical resource availability.
                                 <IP/HOST-ALIAS-NAME> – Configures the IPv4 address or
                                    host alias of the critical resource. Specify the IPv4 address or
                                    host alias name (should be existing and configured). | 
                  
                     | {dhcp vlan
                        {<1-4094>| <VLAN-ALIAS-NAME>]| dns
                        <IP/HOST-ALIAS-NAME>} | The ‘dhcp‘ and
                        ‘dns‘ parameters are recursive and you can optionally configure multiple
                        VLANs and critical resource IPv4 addresses (or host alias names). 
                           dhcp – Optional.
                              Configures DHCP as the mode of monitoring critical resources. When
                              configured, DHCP message flows (DHCP Discover, DHCP Offer, etc.) are
                              used instead of ICMP or ARP packets to confirm critical resource
                                 availability.
                                 vlan
                                    [<1-4094>|<VLAN-ALIAS-NAME>] – Configures the VLAN
                                    on which the critical resource(s) is available. Specify the VLAN
                                    from 1 - 4094. Alternately, use a vlan-alias to identify the
                                    VLAN. If using a vlan-alias, ensure that the alias is existing
                                    and configured.dns – Optional. Configures
                              DNS as the mode of monitoring critical resources. When configured, DNS
                              message flows are used instead of ICMP or ARP packets to confirm
                              critical resource availability.
                                 <IP/HOST-ALIAS-NAME> – Configures the IPv4 address or
                                    host alias of the critical resource. Specify the IPv4 address or
                                    host alias name (should be existing and configured). | 
               
critical-resource monitor interval <5-86400>
                  
                     | monitor interval
                        <5-86400> | Configures the
                        critical resource monitoring frequency. This is the interval between two
                        successive pings to the critical resource being monitored. 
                           <5-86400> –
                              Specifies the frequency in seconds. Specify the time from 5 - 86400
                              seconds. The default is 30 seconds. | 
               
critical-resource retry-count <0-10>
                  
                     | retry-count
                        <0-10> | Configures the maximum number of failed attempts allowed to connect to a critical resource, using DHCP/DNS message flows, before marking it as down 
                           <0-10> – Specifies the maximum number of retries from 0 - 10. The default value is 3 attempts. |
