The CDLC IP channel command word (CCW) area table contains one entry for each active IP router that uses CDLC protocol. Channel programs, device status, and read buffer information reside in this table.
The MAXIPCCW parameter on the SNAKEY macro in CTK2 defines the number of IP CCW area table entries. The size of each IP CCW area is 4096 bytes.
Each active IP router has two sets of read buffers assigned to it for reading packets from the network. The IPRBUFFS parameter on the SNAKEY macro in CTK2 defines the number of read buffers in each set. The IPRBUFSZ parameter on the SNAKEY macro in CTK2 defines the size of read buffer.
