cmEthernetIfAdminStatus
Module: SA-CM-MIB
OID (symbolic): SA-CM-MIB::cmEthernetIfAdminStatus
OID (numeric): 1.3.6.1.4.1.1429.77.1.4.41.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: For RG Mode this MIB provides a way to force the ifAdminStatus.x MIB settings for the individual Ethernet ports to the values stored in cmEthernetAdminStatus.x. This feature is activated by setting cmEthernetIfAdminOverride is set to enable(1).
Bridge mode is a special case since there is only one ifindex = .1 for all 4 ports. In Bridge Mode this MIB still allows you control the port status per Ethernet interface. However, the value of ifAdminStatus.1 and ifOperStatus.1 will follow the following logic: If at least 1 port is set to up by cmEthernetIfAdminStatus.x then ifAdminStatus.x will be set to up(1). If all ports are set to down by cmEthernetIfAdminStatus.x then ifAdminStatus.1 will report down(2). ifAdminStatus.x will report testing(3) if all ports set by cmEthernetIfAdminStatus.x are in testing(3) status.
The major use case for this MIB is to set specific unused ports on the RG to down(2) status immediately after a reboot and prior to CM registration. This MIB is written to non-vol and survives a reboot. A factory reset sets MIB index values back to up(1).
1: up(1) Force the individual port to up(1). 2: down(2) Force the individual port to down(2) 3: testing(3) Force the port to testing status(3) No packets passed.
What is cmEthernetIfAdminStatus?
Read-write per-port override (indexed 1-4) that forces a specific Ethernet port's administrative status to up(1), down(2), or testing(3); it only takes effect once cmEthernetIfAdminOverride is enabled, is commonly used to force unused RG ports down right after boot before CM registration, and survives reboots until a factory reset resets it back to up(1). In Bridge Mode, since all four ports share ifIndex 1, the overall ifAdminStatus/ifOperStatus.1 reported follows special combining logic across all four per-port values.
