Cisco IOS Release 12.0(27)S
Restrictions
When traffic shaping is configured on a VC, the cell delay variation (CDV) is set for the VC. This value
will change according to the shaping class defined. The cell delay variation tolerance (CDVT) values are
shown in
Table 6
.
Note
For VBR connections in which the SCR is not equal to the PCR value, the CDVT is significantly lower.
