CONFIG Commands

receive-buffers interface# max#

 

 

 

Adjusts the number of private receive buffers for most interfaces.

 

The range is 5 to 1000.

 

 

 

Note: This command is not applicable for ISDN Primary Rate Interfaces .

 

For ISDN PRI, the number of receive buffers is ®xed at 5 per

 

B-channel, 115 for T1 and 150 for E1. When in channelized mode,

 

the PRI gets 5 receive buffers per con®gured timeslot.

 

(On some devices, the maximum value is restricted further, as shown in

 

Table 9.) To restore the default, set the value to 0. The set receive-buffers

 

command can be used to increase the receive performance of an interface.

 

In addition, this command can be used to reduce ¯ow control drops when

 

the router is forwarding many packets from a fast interface to a slow

 

interface. The effect of this command is visible on the GWCON buffer

 

command.

 

 

 

 

Attention: Use the set receive-buffercommand only under direct

 

instructions from your service representative.

De®nesn, the number of spare interfaces, for this device. See ªCon®guring

 

Spare Interfacesº on page 44 for additional information.

Time

Use the time command to set the 2210 system clock and date, and to display the values on the user console. These values can then be used to time-stamp ELS messages.

Note: The 2210 has a hardware clock that maintains the date and time after router reinitialization.
