OID list for swap
- mem Total Swap
- memTotalSwap 1.3.6.1.4.1.311.1.1.3.1.1.1.3 (defined in UCD-SNMP-MIB)
The total amount of swap space configured for this host. - mem Available Swap
- memAvailSwap 1.3.6.1.4.1.311.1.1.3.1.1.1.4 (defined in UCD-SNMP-MIB)
The amount of swap space currently unused or available. - mem Total Swap TXT
- memTotalSwapTXT 1.3.6.1.4.1.311.1.1.3.1.1.1.7 (defined in UCD-SNMP-MIB)
The total amount of swap space or virtual memory allocated for text pages on this host. This object will not be implemented on hosts where the underlying operating system does not distinguish text pages from other uses of swap space or virtual memory. - mem Available Swap TXT
- memAvailSwapTXT 1.3.6.1.4.1.311.1.1.3.1.1.1.8 (defined in UCD-SNMP-MIB)
The amount of swap space or virtual memory currently being used by text pages on this host. This object will not be implemented on hosts where the underlying operating system does not distinguish text pages from other uses of swap space or virtual memory. Note that (despite the name), this value reports the amount used, rather than the amount free or available for use. For clarity, this object is being deprecated in favour of 'memUsedSwapTXT(16). - mem Minimum Swap

Compaq Tape Library Hot Swap Status. Hot swap status denotes the presence of hot swappable internal components such as drives, fans, power supplies, etc. The library hot swap status can be in one of the following states: other(1) The library hot swap status is unknown. notSupported(2) Indicates that the library cannot detect or report hot swap status. capable(3) Indicates that the library is capable of detecting and reporting hot swappable internal components and has at least one hot swappable component. notCapable(4) Indicates that the library is capable of detecting and reporting hot swappable internal components but there are no hot swappable components installed. - sys Hw Last Hot Swap Event
- sysHwLastHotSwapEvent 1.3.6.1.4.1.52.2501.1.1.22 (defined in ctron-ssr-hardware-mib)
The value of sysUpTime when the last hotswap of a physical module event occured. - Cisco Adsl ATU-C Dmt Configuration Bit Swap Enabled
- cAdslAtucDmtConfBitSwapEnabled 1.3.6.1.4.1.9.9.130.1.14.1.7 (defined in CISCO-ADSL-DMT-LINE-MIB)
This object specifies whether the ATU-C performs bitswapping. Bitswapping attempts to maintain an acceptable margin for each bin; equalizing the margin across all bins through bit reallocation, thereby maximizing error performance. The ATU-C performs bitswapping by monitoring the margin measured for each bin by the transmitter: 1) If a bin's margin falls below 'target' and the difference, between the margin and 'target' exceeds 'thresh(f)', then the ATU-C marks the bin as a 'from' bin. 2) If a bin's margin exceeds 'target' and the difference between the margin and 'target' exceeds 'thresh(t)', then the ATU-C marks the bin as a 'to' bin. Where: 'target' = adslAtucConfTargetSnrMgn 'thresh(f)' = cAdslAtucDmtConfBitSwapFrom 'thresh(t)' = cAdslAtucDmtConfBitSwapTo The ATU-C attempts to equalize the margin across the bins by swapping bits out of bins marked 'from' into bins marked 'to'. When the ATU-C swaps a bit out of bin, it decreases its b(i). Thus, the bins constellation is smaller, which increases its margin. When the ATU-C swaps a bit into a bin, it increases its b(i). Thus, the bins constellation is larger, which decreases its margin. In addition, the ATU-R may optionally implement its own monitoring capability. The ATU-R uses this information to request the ATU-C to perform bitswapping. When this object is 'true', the ATU-C must be prepared to accept and properly handle bitswap requests from the ATU-R. While bitswapping has its obvious advantages, bitswapping can have undesirable side effects. It can introduce errors on lines prone to impulse noise. In this case, it may be desirable to disable bitswapping. - Cisco Adsl ATU-C Dmt Configuration Bit Swap From
- cAdslAtucDmtConfBitSwapFrom 1.3.6.1.4.1.9.9.130.1.14.1.8 (defined in CISCO-ADSL-DMT-LINE-MIB)
Bitswapping attempts to maintain an acceptable margin for each bin; equalizing the margin across all bins through bit reallocation, thereby maximizing error performance. The ATU-C performs bitswapping by monitoring the margin measured for each bin by the transmitter. If a bin's margin falls below adslAtucConfTargetSnrMgn and the difference between the margin and adslAtucConfTargetSnrMgn exceeds the value of this object, then the ATU-C marks a bin as a 'from' bin. The ATU-C attempts to equalize the margin across the bins by swapping bits out of bins marked 'from' into bins marked 'to'. When the ATU-C swaps a bit out of bin, it decreases its b(i). Thus, the bins constellation is smaller. which increases its margin. When the ATU-C swaps a bit into a bin, it increases its b(i). Thus, the bins constellation is larger, which decreases its margin. If this value is too small, then the ATU-C may frequently toggle the bit allocation on bins, and if impulse noise is present, this can cause errors. If this value is too large, then the ATU-C may not identify an adequate number of bins that it can swap bits 'from', thereby decreasing the chances for the ATU-C to equalize the margin across all the bins. Unequalized margin across all the bins translates into poor error performance. - Cisco Adsl ATU-C Dmt Configuration Bit Swap To
- cAdslAtucDmtConfBitSwapTo 1.3.6.1.4.1.9.9.130.1.14.1.9 (defined in CISCO-ADSL-DMT-LINE-MIB)
