Server Load Balancing Operations Menu Options (/oper/slb) 
Command Syntax and Usage
group <real server group ID (alphanumeric)>
 
Displays the Real Server Group menu. To view this menu, see /oper/slb/group Real Server Group Operations.
gslb
 
Displays the Global SLB Operations menu. To view this menu, see /oper/slb/gslb Global SLB Operations Menu.
sync
 
Available only when there is at least one peer enabled.
Synchronizes the SLB, filter, VRRP, port, Bandwidth Management configuration, and virtual router (VR) priorities on a peer (an Alteon that is associated with the IP address). To take effect, peers must be configured on Alteon and the administrator password on the peers must be identical.
Note: For a dedicated (non-virtual) ADC and for vADC instances, this command is executed through a data port and cannot be executed from the management interface.
ena <real server ID (alphanumeric)>
 
Temporarily enables a real server. The real server is returned to its configured operation mode when Alteon is reset.
dis <real server ID (alphanumeric)> [P - allow persistent http 1.0 sessions] p|n
 
Temporarily disables real servers. The real server is returned to its configured state after an Alteon reset. This provides for orderly server shutdown to allow maintenance on a server. For more information, see Disabling and Enabling Real Servers in the Alteon Command Line Interface Application Guide.
Values:
*p — Persistent. Immediately suspends assignment of connections to the specified real server (except for persistent HTTP 1.0 sessions) by removing the real server from operation within its real server group and virtual server.
*n — None. Immediately suspends assignment of connections to the specified real server by removing the real server from operation within its real server group and virtual server.
sessdel
 
Marks the session table entry for fastage. The entry is deleted later during fastage scanning.
To delete an entry from the session table immediately, use the /oper/slb/clear command.
sessdel6
 
Deletes the IPv6 session table entry.
psessdel [<cookie ID from p-entry>|ip|sslid]
 
Deletes persistent entries from the session table.
Values:
*cookie — Deletes a specified insert/rewrite cookie entry from the session table.
*ip — Deletes a specified real server entry from the session table.
*sslid — Deletes a specified SSL session entry from the session table.
sessmov
 
Enables you to move the session entries of a specific client IP address, including persistency entries, from the current real server to another real server in the same group. This is a scenario that can be useful for IPSec sessions. The time required to move the session between servers is according to the fastage time configured.
b64encode <cookie ID from p-entry>
 
The cookie insert and rewrite mechanism records each cookie it generates as a persistence entry (p-entry) in the session table.
This command encodes the cookie as a base64 string.
b64decode <cookie value from the http packet>
 
The cookie insert and rewrite mechanism records each cookie it generates as a persistence entry (p-entry) in the session table.
This command decodes the cookie from a base64 string.
smirror
 
Sends a request for an update from the VRRP backup Alteon to the VRRP primary. This request is sent to avoid sessions on the backup Alteon that can be updated only by a VRRP failover or an Alteon reset.
Note: VRRP must be enabled and Alteon must be a VRRP backup, otherwise this command returns an error message.
clear (active | all)
 
Clears all session tables. When both the following conditions are met, you can also clear all session tables on the HA peer:
*/cfg/l3/hamode is set to service.
*Session mirroring is enabled for at least one service.
Default: active
ddstore
 
Displays the Dynamic Data Store Operations menu. To view this menu, see /oper/slb/ddstore Dynamic Data Store Operations Menu.
cachpurg
 
When the caching criteria or the server content has changed, you may want to purge the cached content of HTTP responses. You can purge the cache for:
*All virtual servers and their virtual services
*All virtual services for a specific virtual server (virt number)
*For a specific service (virtual server and virtual service)
*For a specific object URL or a URL with wildcard in it (*)
At the prompt, enter the caching policy ID to purge the cache for a particular caching policy, or all to purge the cache for all caching policies.
For more information on caching policies, see the section on caching policies in the Alteon Command Line Interface Application Guide, and /cfg/slb/accel/caching/cachepol <policy ID (alphanumeric)> Caching Policy Menu.
ocsppurg
 
When the OCSP cache is filled with stale responses, you may want to purge the cache.
At the prompt, enter the client authentication policy ID to purge the cache for a particular client authentication policy, or all to purge the cache for all client authentication policies.
For more information on client authentication policies, see the section on client authentication policies in the Alteon Command Line Interface Application Guide, and /cfg/slb/ssl/authpol Authentication Policy Menu.
Note: If the same client certificate arrives at two different SPs, an OCSP query is sent to the OCSP that responded, even if the OCSP is cache enabled.
cdppurg
 
Purges CDP cached information (last CRL file fetch).
clrpeak
 
Clears SSL CPS and compression throughput peak values.
cur
 
Displays the current SLB operational state.
trevnt <virtual server id> <virtual service port > <cef|json>
 
With this traffic event test command, a self-generated unified event is sent to the rlogging server defined at the traffic event policy associated with this service.
This command allows easy debugging of the traffic event connectivity without the need to send real traffic from a client.
The self-generated event only includes the mandatory parameters required to identify the application.
You are required to enter the virtual server ID, virtual port (10-65534) and event format (cerf or json).
