A table containing information about each managed ethernet connectivity port on a board. The number of entries is determined by the number of managed ports. Those boards that do not have any ports do not have any entries in this table.

A row in Ethernet port table. Entries can not be created or deleted via SNMP.

The index of the board. This corresponds to the index of the slot containing the board.

The index of the port on the board. Its value ranges between 1 and index of the last manageable port on the board.

The partition status of the port. The following values can be written: enabled(2)..........enabled port partition(3)........partition port timedPartition(5)...time partition port (uses value from s5EnPortPartTime) The following values reflect the partition status of the port: other(1).............partition status unknown enabled(2)...........port enabled partition(3).........port partitioned autoPartition(4).....port auto-partitioned by hardware timedPartition(5)....port is timed partitioned (see value of s5EnPortPartTime). On GETs with port status of timedPartition(5), if the time remaining before the partition is undone is available, it will be reported in object s5EnPortPartTime as a positive value. If not available, the value of s5EnPortPartTime will be zero. When changing a port to timedPartition(5), the SET request must also contain the value for object s5EnPortPartTime. Only value partition(3) will survive resets of the host card. Enumeration: 'autoPartition': 4, 'other': 1, 'enabled': 2, 'timedPartition': 5, 'partition': 3.

The length of time to keep the port partitioned when a timed partition is done to the port. This object can only be written in the same request that sets s5EnPortPartStatus to timedPartition(5). Afterwards, it indicates the amount of time left before the timed partition is completed, at which time s5EnPortPartStatus is changed to enabled(2). This object has the value of zero if the port is not time partitioned, or if the amount of time is not available.

Tells whether the port is receiving link status. The values are: other(1)...returned for AUI off(2).....link is not connected on(3)......link is connected on/off applies to 10BASE-T and Fiber ports only. Enumeration: 'on': 3, 'other': 1, 'off': 2.

The jabber status of the DTE(s) connected to the port. The values are: other(1).......unknown or other condition jabbering(2)...port receiving jabber ok(3)..........no jabber detected. Enumeration: 'other': 1, 'ok': 3, 'jabbering': 2.

An extension table to s5EnPortTable containing additional information about per port switchable, autonegotiating 10/100 Mbit ethernet connectivity ports on a board. The number of entries is determined by the number of managed ports. Those boards that do not have any ports do not have any entries in this table.

A row in Ethernet port extension table. Entries can not be created or deleted via SNMP.

The index of the board. This corresponds to the index of the slot containing the board.

The index of the port on the board. Its value ranges between 1 and index of the last manageable port on the board.

A bit array that contains the bit map representing the hardware capabilites of the port. The bit 7 tells if the port supports auto-negotiation. If the auto negotiation is on, the port will have multiple speed capabilities while if the auto negotiation is not supported, the hardware will only be capable for one speed: bit 0 - 10 BASE-T half duplex capable bit 1 - 10 BASE-T full duplex capable bit 2 - 100 BASE-TX half duplex capable bit 3 - 100 BASE-TX full duplex capable bit 5 - 100 BASE-FX full duplex capable bit 6 - 100 BASE-FX half duplex capable bit 7 - auto negotiation support capability When auto negotiation is supported only bits 0-3 are used to indicate the capabilities available for negotiation, and any or all of these bits may be set as long as at least one bit is set. When auto negotiation is NOT supported (bit 7 = 0) all other bits are used to indicate the capabilities supported by the port, but which must be manually configured.

A bit array that contains the bit map representing the abilities advertised during link negociation. The bit 7 tells if auto negotiation is enabled or disabled: bit 0 - 10 BASE-T half duplex capable bit 1 - 10 BASE-T full duplex capable bit 2 - 100 BASE-TX half duplex capable bit 3 - 100 BASE-TX full duplex capable bit 5 - 100 BASE-FX full duplex capable bit 6 - 100 BASE-FX half duplex capable bit 7 - auto negotiation is enabled or disabled Only capabilites present in the hardware as indicated by s5EnPortExtHwCapability can be advertised. If auto negotiation is enabled only bits 0-3 are used to indicate the capabilities available for negotiation. Any or all of these bits may be set as long as at least one bit is set, AND the settings are in accordance with s5EnPortExtHwCapability. If auto negotiation is disabled one and only one of the speed setting bits MUST be set in accordance with s5EnPortExtHwCapability.

A bit array that contains the bit map representing the auto-negotiation abilities of the remote end of the link: bit 0 - 10 BASE-T half duplex capable bit 1 - 10 BASE-T full duplex capable bit 2 - 100 BASE-TX half duplex capable bit 3 - 100 BASE-TX full duplex capable

The index for the segment used in case a 10 Mbit link is established.

The index for the segment used in case a 100 Mbit link is established.

A bit array that contains the bit map representing all available 10Mbit backplane segment and local segment connections for the port. One bit is also reserved to indicate if the cluster has an isolate capability. The first 31 bits of the array represent the backplane numbers, starting from the lower order bit. Bit 32 indicates whether the port has a null connection capability. The bits in the fifth and sixth octets, starting with bits in the lower order octet, represent local segments that the port can connect to. A bit with a value of 1 means that the port is capable of connecting to the corresponding backplane segment, local segment or null segment.

Bit 32 indicates whether the port has a null connection capability.
