show sdllc local-ack
To display the current state of any current local acknowledgment connections, and any configured pass-through rings, use the show sdllc local-ack command in privileged EXEC mode.
show sdllc local-ack
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
Examples
The following is sample output from the show sdllc local-ack command:
Router# show sdllc local-ack
local 1000.5a59.04f9, lsap 04, remote 4000.2222.4444, dsap 04
llc2 = 1798136, local act state = connected
Passthrough Rings: 4 7
In the display, the first two lines of the show sdllc local-ack command show that there is a local acknowledgment session between two Token Ring devices. The device on the local ring has a MAC address of 1000.5a59.04f9 with a service access point (SAP) of 04. The remote device has a MAC address of 4000.2222.4444 with a SAP of 04. The state of the local acknowledgment session is connected.
The pass-through rings display is independent of the rest of the show sdllc local-ack command. The pass-through rings display indicates that there are two rings, 4 and 7, configured for pass-through. This means that stations on these rings will not have their sessions locally acknowledged but will instead have their acknowledgments end-to-end.
Table 89 describes the significant fields shown in the display.
show sna
To display the status of the Systems Network Architecture (SNA) Service Point feature, use the show sna command in privileged EXEC mode.

FRAMES RECEIVED 0450 FRAMES SENT 0010
LUs USED BY DSPU nnn LUs ACTIVE nnn
LUs USED BY API nnn LUs ACTIVE nnn
LUs ACTIVATED BY HOST BUT NOT USED nnn
Because the all keyword refers to logical unit (LU)s under the physical unit (PU), this has no significance for the service point host.

Usage Guidelines
HPR RTP pipes use a unique flow and congestion control algorithm called ARB flow control. ARB allows HPR pipes to measure the network's level of congestion and dynamically adjust the rate of data input into the network, so that the network is highly utilized and congestion is avoided. If actual losses occur, ARB can also react to those losses.

Command History
Usage Guidelines
The keywords and arguments that are available with the show spanning-tree command vary depending on the platform you are using and the network modules that are installed and operational.
Cisco 2600, 3660, and 3845 Series Switches
The valid values for interface interface-type are:
•fastethernet—Specifies a Fast Ethernet IEEE 802.3 interface.
•port-channel—Specifies an Ethernet channel of interfaces.
Cisco 6500/6000 Catalyst Switches and 7600 Series Routers
The port-channel number values from 257 to 282 are supported on the Content Switching Module (CSM) and the Firewall Services Module (FWSM) only.
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
When checking spanning tree-active states and you have a large number of VLANs, you can enter the show spanning-tree summary total command. You can display the total number of VLANs without having to scroll through the list of VLANs.
The valid values for interface interface-type are:
•fastethernet—Specifies a Fast Ethernet IEEE 802.3 interface.
•port-channel—Specifies an Ethernet channel of interfaces.
•atm—Specifies an Asynchronous Transfer Mode (ATM) interface.
•gigabitethernet—Specifies a Gigabit Ethernet IEEE 802.3z interface.
•multilink—Specifies a multilink-group interface.
•serial—Specifies a serial interface.
•vlan—Specifies a catalyst VLAN interface.
The valid values for keyword pathcoast method are:
•append—Appends the redirected output to a URL (supporting the append operation).
•begin—Begins with the matching line.
•exclude—Excludes matching lines.
•include—Includes matching lines.
•redirect—Redirects output to a URL.
•tee—Copies output to a URL.
When you run the show spanning-tree command for a VLAN or an interface the switch router will display the different port states for the VLAN or interface. The valid spanning-tree port states are listening, learning, forwarding, blocking, disabled, and loopback. See Table 0-92 for definitions of the port states:

shutdown (CMCC)
To shut down an interface or the virtual interface on the Cisco Mainframe Channel Connection (CMCC) adapter when the router is in interface configuration mode, use the shutdown command in interface configuration mode. The shutdown TN3270 server command also shuts down TN3270 entities, such as physical unit (PU), Dependent Logical Unit Requestor (DLUR), and DLUR service access point (SAP), depending on which configuration mode the router is in when the command is issued. To restart the interface or entity, use the no form of this command. The entity affected depends on the mode in which the command is issued.
shutdown
no shutdown
Syntax Description
This command has no arguments or keywords.
Defaults
The interface or entity is enabled.
Command Modes
