To prevent ingress traffic on a router while the IS reload is implemented, use the following command.

Enabling and Disabling a Port using SNMP

To enable and disable a port using SNMP, use the following commands.
1 Create an SNMP community on the Dell system.
CONFIGURATION mode
snmp-server community
2 From the Dell Networking system, identify the interface index of the port for which you want to change the admin status.
EXEC Privilege mode
show interface
Or, from the management system, use the snmpwwalk command to identify the interface index.
3 Enter the snmpset command to change the admin status using either the object descriptor or the OID.
snmpset with descriptor: snmpset -v version -c community agent-ip ifAdminStatus.ifindex i {1
| 2}
snmpset with OID: snmpset -v version -c community agent-ip .1.3.6.1.2.1.2.2.1.7.ifindex i {1
| 2}
Choose integer 1 to change the admin status to Up, or 2 to change the admin status to Down.
