Define SNA LLC
The following are CLI commands for managing an LLC2 port. These parameters configure the BAN encapsulation and the LLC2 transport.
CLI> define sna llc portName
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <PortName> | "String" (1..8) | Enter the name of this port as a quoted string. The name must contain only ASCII printable characters and must be unique for each LLC2 port. |
CLI> define sna llc t2AckDelayTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <T2AckDelayTimer> | Integer (0..65535) | This is the default acknowledgement timer. Enter the maximum time in milliseconds to wait before sending an acknowledgement for a sequenced PDU. 0 means no delay for acknowledgement. The default is 300. |
CLI> define sna llc ackTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <AckTimer> | Integer (1..65535) | This is the maximum time, in milliseconds, that the LLC2 port should expect an acknowledgement to a transmitted I-frame. The default is 5000. |
CLI> define sna llc rcvWindow
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <RcvWindow> | Integer (0..127) | The default receive window size. Enter the maximum number of unacknowledged I-frames that may be received. 0 tells the Passport 4400 unit to use the value determined by the switching component. The default is 7. |
CLI> define sna llc pbitTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <PbitTimer> | Integer (0..65535) | The time in milliseconds to wait for a response to a frame sent with the poll bit set. The default is 5000. |
CLI> define sna llc rejTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <RejTimer> | Integer (0..65535) | The time in seconds to wait for a response to a reject frame. The default is 5. |
CLI> define sna llc busyTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <BusyTimer> | Integer (0..65535) | The time in seconds that the LLC2 port waits for an indication of clearance of a busy condition at the adjacent link station. The default is 5. |
CLI> define sna llc inactTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <InactTimer> | Integer (0..65535) | The time in seconds that a Receiver Ready keep alive frame is sent on an idle link. The default is 30. |
CLI> define sna llc xidTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <XIDTimer> | Integer (0..65535) | Enter the time in seconds between XID retries. The default is 6. |
CLI> define sna llc xidRetries
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <XIDRetries> | Integer (0..65535) | Enter the maximum number of XID retries. 65535 means the XID retries will continue indefinitely. The default is 10. |
CLI> define sna llc testTimer
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <TESTTimer> | Integer (0..65535) | Enter the interval in seconds between TEST retries. The default is 6. |
CLI> define sna llc testRetries
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <TESTRetries> | Integer (0..65535) | Enter the maximum number of TEST retries. 65535 means the TEST retries will continue indefinitely. The default is 10. |
CLI> define sna llc newWindowAcks
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <NewWindowAcks> | Integer (1..127) | Enter the number of I-frames that must be acknowledged before the dynamic window algorithm increments the current working window size. The default is 4. |
CLI> define sna llc maxRetries
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <MaxRetries> | Integer (0..65535) | Enter the maximum number of times an attempt is made to retransmit a response across the interface. This parameter affects llcPortAckTimer, llcPortPbitTimer, llcPortRejTimer, and llcPortBusyTimer. The default is 5. |
CLI> define sna llc localRingNum
| Parameter | Range of Values | Required Action |
| <IfIndex> | Integer (1..255) | Enter the IfIndex of the port. |
| <LocalRingNum> | Integer (0..4095) | Enter the number of the ring (Token Ring) to which the Passport 4400 unit is connected. This will make the Passport 4400 SNA services interoperate with third party routers over RFC 1490. The default is 0. |
