**Table 1** Description of the **display slb group verbose grp1** command output
Item	Description
Group Name	Server group name
Group ID	Server group ID
Metric	Load balancing algorithm. In the real server group view, run the metric command to set this parameter.
Source-nat Type	Source NAT mode: outbound interface or address pool. "NA" indicates that source NAT is not configured.
Health Check Type	Health check protocol type. In the real server group view, run the health-check type command to set this parameter.
Real Server Number	Number of real servers in a group
Current Connection	Total number of concurrent connections on all servers in a group
RserverID	Real server ID. In the real server group view, run the reserver command to set this parameter.
IP Address	Real server IP address. In the real server group view, run the reserver command to set this parameter.
Weight	Real server weight. In the real server group view, run the reserver command to set this parameter.
Status	Real server status A real server has the following statuses: Admin-Active: The real server is available. The real server is not specified as unavailable (status inactive) and health check parameters are not configured. Therefore, the real server is available by default. Admin-Active: The real server is unavailable. The real server is specified as unavailable (status inactive). No matter whether the health check parameters are configured or not and what the check result is, the real server is unavailable. The highest priority is configured for status inactive. Admin-Health-Check: indicates the transitive status of health check. Health check is implemented on the server, but no result is available yet. Active: The real server is available. Health check is implemented on the server, and the result shows that the real server is available. Inactive: The real server is unavailable. Health check is implemented on the server, and the result shows that the real server is unavailable. In the real server group view, run the reserver command to specify the real server as unavailable (inactive) or implement health check for the real server (health-check). By default, the status of the real server is health-check.
Max-connection	Maximum number of connections on a real server. "-" indicates that this parameter is not configured. In the real server group view, run the reserver command to set this parameter.
Ratio	Percentage of a real server's service traffic in the total traffic in the last 5 minutes. The statistics can be cleared using reset slb statistics.
TotalSession	Number of new sessions on a real server in the last 5 minutes. The measurement time point of TotalSession is different from that of Ratio. The statistics can be cleared using reset slb statistics.
CurSession	Number of current sessions on a real server. The statistics cannot be cleared using reset slb statistics.
