undo ip route-static ip-address { mask | mask-length } [ interface-type interface-number | next-hop ] [ preference preference-value ]
View
System view
Parameters
ip-address: IP address in dotted decimal notation.
mask: Subnet mask.
mask-length: Length of the subnet mask, that is, the number of successive bits in the subnet mask whose values are 1.
interface-type interface-number: Interface type and interface number.
next-hop: Next hop IP address in dotted decimal notation.
preference-value: Priority of the route. This argument ranges from 1 to 255.
reject: Specifies the route to be unreachable. If you specify this keyword when executing this command, any packet destined for the specified IP address is discarded, and the system informs the source that the destination is unreachable.
blackhole: Specifies the route to be a blackhole route. If you specify this keyword when executing this command, all outbound interfaces of the static route are the NULL 0 interfaces regardless of the next hop. In addition, the system discards any packet transmitted along this route without informing the source.
group-number: Detected group number ranging from 1 to 25.
Description
Use the ip route-static detect-group command to configure a static route, whose validity depends on detecting results as follows:
l The route is valid when the detecting result is reachable.
l The route is invalid when the detecting result is unreachable.
Use the undo ip route-static command to remove an existing static route.
Examples
# Configure a static route to 192.168.1.5/24 with 192.168.0.2 as the next hop, and control the static route validity using the detecting result of detected group 10.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] ip route-static 192.168.1.5 24 192.168.0.2 detect-group 10
After the configuration, if detected group 10 is reachable, the static route is valid; if detected group 10 is unreachable, the static route is invalid.
option
Syntax
option [ and | or ]
undo option
View
Detected group view
Parameters
and: Specifies the relationship between detected objects as logic AND, which means that the detecting result is reachable only when all the detected objects contained in the detected group are reachable.
or: Specifies the relationship between detected objects as logic OR, which means that the detecting result is reachable if one of the detected objects contained in the detected group is reachable.
Description
Use the option command to specify the way to generate detecting results.
Use the undo option command to restore the default way to generate detecting results.
By default, the relationship between the detected objects is and.
When a detecting operation is being carried out, the switch detects each detected object contained in the detected group in turn by their sequence number.
l If you specify the and keyword, the switch returns reachable as the detecting result only if all the detected objects in the detected group are detected reachable.
l If you specify the or keyword, the switch returns reachable as the detecting result only if one of the detected objects in the detected group is detected reachable and the remaining detected objects will not be detected any more.
Examples
# Specify the relationship between the three detected objects in detected group 10 as or.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] detect-group 10
[Sysname-detect-group-10] detect-list 1 ip address 202.13.1.55 nexthop 1.2.3.4
[Sysname-detect-group-10] detect-list 2 ip address 202.13.1.56 nexthop 1.2.3.4
[Sysname-detect-group-10] detect-list 3 ip address 202.13.1.57 nexthop 1.2.3.4
[Sysname-detect-group-10] option or
After the configuration, if one of the three detected objects is reachable, the system will consider detected group 10 reachable.
retry
Syntax
retry retry-times
undo retry
View
Detected group view
Parameters
retry-times: Maximum retry times during a detect operation. This argument ranges from 0 to 10 and defaults to 2.
Description
Use the retry command to set the maximum retry times during a detect operation. Use the undo retry command to restore the default times.
By default, the maximum retry times during a detect operation is two.
Examples
# Specify the maximum number of retires to 3 for detected group 10.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] detect-group 10
[Sysname-detect-group-10] retry 3
standby detect-group
Syntax
standby detect-group group-number
undo standby detect-group
View
VLAN interface view
Parameters
group-number: Detected group number ranging from 1 to 25.
Description
Use the standby detect-group command to configure the interface backup function by using the auto detect function.
Use the undo standby detect-group command to disable the interface backup function.
After you configure the standby detect-group command, whether the backup interface is enabled depends on the auto detecting results:
l The primary interface keeps in use when the detected group is reachable.
l The backup interface is enabled when the detected group is unreachable.
l The backup interface is disabled and the primary interface is re-enabled when the link between the primary interface and the destination resumes, that is, the detected group is reachable again.
Examples
# Specify to enable VLAN-interface 2 (the backup interface) when the detected group 10 is unreachable.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] standby detect-group 10
After the configuration, if detected group 10 is reachable, the backup interface VLAN-interface 2 will be in the disabled state, and if detected group 10 is unreachable, VLAN-interface 2 will be enabled.

vrrp vrid track detect-group
Syntax
vrrp vrid virtual-router-id track detect-group group-number [ reduced value-reduced ]
undo vrrp vrid virtual-router-id track detect-group [ group-number ]
View
VLAN interface view
Parameters
virtual-router-id: Virtual router ID ranging from 1 to 255.
group-number: Detected group number ranging from 1 to 25.
value-reduced: Value by which the priority is to be reduced. This argument ranges from 1 to 255 and defaults to 10.
Description
Use the vrrp vrid track detect-group command to specify an auto detected group for a VRRP group.
Use the undo vrrp vrid track detect-group command to cancel the configuration.
You can enable Auto Detect on the master switch in a VRRP group, use the Auto Detect function to detect the links from the master to other networks, and use the detection results (reachable/unreachable) to control the priority of the master, so as to realize the automatic master-backup switchover:
l The master keeps as master when the detected group is reachable.
l The priority of the master decreases and thus becomes a backup when the detected group is unreachable.
Currently, auto detect in VRRP is only supported in S3600-EI series Ethernet switches.
Examples
# Specify to decrease the priority of the master switch in VRRP group 1 by 20 when the detected group 10 is unreachable.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] vrrp vrid 1 track detect-group 10 reduced 20
After this configuration, if detected group 10 is reachable, the master keeps as master, and if detected group 10 is unreachable, the master decreases its priority by 20 and becomes a backup.
