The EtherSwitch 1420 hot-swappable modules provide a choice of FDDI and 100BaseT connections that support Category 5 UTP or fiber-optic cabling. This chapter describes the MIB objects used to configure and manage these modules.
This group is used to manage the high-speed expansion modules in the EtherSwitch 1420 expansion slots. Any attempt to manage an EtherSwitch 1420 without modules using this group results in an error. This group provides configuration, status, and control objects for the overall unit.
This read-only MIB object displays the number of expansion slots that are available in the unit.
| Valid Values: | 2 |
This read-only MIB object identifies the module for which this entry contains information. This value is never greater than esModuleCapacity.
This read-only MIB object displays the current operational status of the port. This value is exactly the same as the swPortStatus for the associated switched port.
This read-write MIB object is used to change the port status to either:
|
Valid Values: | enabled | (1) |
| disabled | (2) |
This value is the same as swPortAdminStatus for the corresponding switched port.
This read-only MIB object displays a text string that includes the full name and version identification of the module's hardware type.
This read-only MIB object displays a text representation of the specified identifier for the installed module or notPresent.
Valid Values: | 110 SingleUTP |
| 101 SingleFiber | |
| 140 FourUTP | |
| 104 FourFiber | |

This read-only MIB object displays the vendor's authoritative identification of the module.
This read-only MIB object displays the number of external port attachments provided by the module (the object sysInfoTotalNumberOfPorts is the sum of this object, for each module, plus 25 for the built-in 10-Mbps ports).
Setting this read-write MIB object to reset forces the module into a reset state. The reset state is a module-specific condition in which the module's packet operations cease while the module resets to a known state. Setting this object to noReset has no effect. The EtherSwitch 1420 always returns the value noReset when this object is read.
| Valid Values: | reset | (1) |
| noReset | (2) |
This read-only MIB object contains the value of sysUpTime at the time that the value of the esModuleStatus object for this module last changed. A value of zero indicates that the group's operational status has not changed since the agent last restarted.
This read-only MIB object contains the number of times the firmware has toggled the module's collision LED from off to on.
This read-only MIB object displays a bit array where the presence of a particular bit indicates a link LED is on for a module port.
Each octet within the value of this object specifies a set of 8 link LEDs, with the first octet specifying link LEDs for ports 1 through 8, the second octet specifying link LEDs 9 through 16, and so on. Within each octet, the most significant bit represents the lowest numbered LED, and the least significant bit represents the highest numbered LED. Thus, each LED is represented by a single bit within the value of this object. If the bit has a value of 1, then the LED is currently on; if the valule is 0, the LED is off.
This read-only MIB object displays a bit array where the presence of a particular bit indicates a disabled LED is on for a module port.
Each octet within the value of this object specifies a set of 8 link LEDs, with the first octet specifying link LEDs for ports 1 through 8, the second octet specifying link LEDs 9 through 16, and so on. Within each octet, the most significant bit represents the lowest numbered LED, and the least significant bit represents the highest numbered LED. Thus, each LED is represented by a single bit within the value of this object. If the bit has a value of 1, then the LED is currently on; if the value is 0, the LED is off.
This MIB object applies to the EtherSwitch 1420 and 1220 only.
This read-only MIB object is the current broadcast-forwarding status of the module. If the module is blocked by Broadcast Storm Control, the switch drops all broadcast packets received from it.
