cesBufMaxSize
Module: CISCO-WAN-AXIPOP-MIB
OID (symbolic): CISCO-WAN-AXIPOP-MIB::cesBufMaxSize
OID (numeric): 1.3.6.1.4.1.351.110.5.3.2.1.1.1.10
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Specifies the maximum size in octets of egress buffer.
CESM - 4P:
Should be at least 0.6*CDVRxT for a T1 line and
0.7 * CDVRxT for a E1 line. 0 can be specified to internally
compute the value
Defaults for CESM-8T1E1 and CESM-T3E3
-------------------------------------
Default value of cesBufMaxSize is 0.
Maximum value for CESM-8T1E1 and CESM-T3E3
-------------------------------------------
For T1 UDT and E1 UDT : 16224 bytes
For T1 SDT : 384 * N bytes
For E1 SDT : 417 * N bytes
For T3 UDT and E3 UDT : 16224 bytes
where N is the number of timeslots assigned in Nx64
connection. For T1-UDT and E1 UDT use N = 32 .
Minimum value for CESM-8T1E1 and CESM-T3E3
-------------------------------------------
In CESM-8T1/E1 and CESM-T3E3 this object ( unit in bytes ) should be at
least the greater of
(1) CDVT in frames * 2 * N
(2) ( CDVT in frames + number of frames in two cells ) * N
where N is the number of timeslots assigned in Nx64
connection. For T1-UDT and E1-UDT use N = 32.
What is cesBufMaxSize?
This read-write value sets the maximum size, in octets, of the channel's egress reassembly buffer, with 0 telling the card to internally compute an appropriate size based on cesCDVRxT, and hard maximums that differ by mode, such as 16224 bytes for T1/E1 unstructured or a per-timeslot formula (384*N or 417*N) for structured mode. An administrator typically leaves this at the default of 0 to let the card size the buffer automatically based on the configured jitter tolerance, only overriding it when a specific buffer size is required for interoperability. For example, on a CESM-4P T1 channel the buffer should be sized to at least 0.6 times cesCDVRxT to properly absorb expected cell arrival jitter.
