Removing a traffic descriptor
To remove a traffic descriptor, use the td free command:
Note: A traffic descriptor that is in use cannot be freed. First, you will need to free
the VCLs that are using the traffic descriptor.
Listing the traffic descriptors
To list all traffic descriptors, use the td show command:
The td show command displays the information described in Table 8.5.
Parameters: <td_id> An unique identifier for this traffic descriptor.
<pcr0+1> The combined PCR for all cells regardless of whether the CLP bit is set
in the ATM cell header.
<scr0> The SCR for cells where the CLP bit is not set.
<mbs0> The MBS for cells where the CLP bit is not set.
Command: M15-155s8:/>td free <td_id>
Example: M15-155s8:/>td free 1
Parameter: <td_id> An identifier for the traffic descriptor.
Command: M15-155s8:/>td show
Output: --ID-- --Count---SRC- ---Quality of Service----
1 7 Int UBR=UBR(Unknown): Best Effort Traffic
2 0 Int No service!
3 7 Auto UBR(Best-Effort): PCR0+1=127
4 3 Auto UBR(Best-Effort): PCR0+1=255
