Use the commands in this chapter to configure XRemote on your communication server. For XRemote configuration information and examples, refer to the chapter "Configuring XRemote" in the Access and Communication Servers Configuration Guide. For information about establishing XRemote connections, refer to the Cisco Access Connection Guide.
To display XRemote connections and monitor XRemote traffic through the communication server, use the show xremote EXEC command.
show xremoteThis command has no arguments or keywords.
EXEC
The show xremote command displays XRemote parameters applied to the entire system, as well as statistics that are pulled for all active XRemote connections.
The following is sample output from the show xremote command when XRemote is enabled on a communication server and XRemote sessions are active:

See Table 16-1 in the show xremote command description earlier in this chapter for show xremote line output field descriptions.
To change the buffer size used for loading font files, use the xremote tftp buffersize global configuration command. To restore the buffer size to the default value, use the no form of this command.
xremote tftp buffersize buffersize
buffersize | (Optional) Buffer size in bytes. This is a decimal number in the range from 4096 to 70000 bytes. |
70000 bytes
Global configuration
When the X terminal requests that a font file be loaded, the communication server must first load the font file into an internal buffer before passing it to the X terminal. The default value of 70000 bytes is adequate for most font files, but the size can be increased as necessary for nonstandard font files.
The buffer size can be set as low as 4096 bytes and as large as the available memory on the communication server will allow. If you are using LAT font access, you should not lower the buffer size below the default, because the font directory for all of the LAT fonts (created internally) requires 70000 bytes.
This command applies to both TFTP and LAT font access.
The following example sets the buffer size to 20000 bytes:
xremote tftp buffersize 20000
To add a specific TFTP font server as a source of fonts for the terminal, use the xremote tftp host global configuration command. To remove a font server from the list, use the no form of this command.
xremote tftp host hostname
hostname | IP address or name of the host containing fonts. |
No TFTP font server is specified.
Global configuration
Each time a new host name is entered, the list on the communication server is updated. Font servers are queried in the order of their definition when the X terminal requests a font.
The following example sets the host IBM-1 as an XRemote TFTP font server:
xremote tftp host IBM-1
The following example sets the host with IP address 1.0.0.7 as an XRemote TFTP font server:
xremote tftp host 1.0.0.7
To specify the number of retries the font loader will attempt before declaring an error condition, use the xremote tftp retries global configuration command. To restore the default retries number, use the no form of this command.
xremote tftp retries retries
retries | (Optional) Number of retries. Acceptable values are decimal numbers in the range from 1 to 15. |
3 retries
Global configuration
Under certain conditions, you might need to increase the number of retires, particularly if the font servers are known to be heavily loaded.
The following example sets the font loader retries to 5:
xremote tftp retries 5
