Configuring CTX Buffers The CTX is an output-buffered switch, with a 64K cell buffer capacity. The software sets up a default configuration, but you can change it if you want. For example, you should make the queue (buffer) used for your router traffic as large as possible. To do this, you must first deallocate memory from another queue—OC3/STM-1 queue 3, for example—and reallocate the memory to the queue that will carry your router traffic. See “CTX Output Queues and Memory Partition” in Appendix B, for reference information pertaining to configuring the output buffers.

To change the default output buffer configuration, follow these steps:

1From the Configuration Management menu, select [1] Manage Card to display the List Card menu.

2Select [2] CTX to display the CTX menu, shown above in Figure 54.

3From the CTX menu, select [2] Manage Buffers. The CTX Buffers menu, shown in Figure 56, appears.
