Description
|
Total of 300 station blocks
|
Total number of forwarding database elements in the system. The memory to hold bridge entries is allocated in blocks of memory sufficient to hold 300 individual entries. When the number of free entries falls below 25, another block of memory sufficient to hold another 300 entries is allocated. Therefore, the size of the bridge forwarding database is limited to the amount of free memory in the router.
|
295 free
|
Number in the free list of forwarding database elements in the system. The total number of forwarding elements is expanded dynamically, as needed.
|
BG
|
Bridging group to which the address belongs.
|

|
Address
|
Canonical (Ethernet ordered) MAC address.
|
Action
|
Action to be taken when that address is looked up; choices are to discard or forward the datagram.
|
Interface
|
Interface, if any, on which that address was seen.
|
Age
|
Number of minutes since a frame was received from or sent to that address. The letter "P" indicates a permanent entry. The letter "S" indicates the system as recorded by the router. On the modular systems, this is typically the broadcast address and the router's own hardware address; on the IGS, this field will also include certain multicast addresses.
|
RX count
|
Number of frames received from that address.
|
TX count
|
Number of frames forwarded to that address.

•NOT_FOUND—Negative caching is on, and the station has not responded to queries.
•UNCONFIRMED—Station is configured, but DLSw has not verified it.
•VERIFY—Cache information is being verified because cache is going stale, or the user configuration is being verified.
|
Loc.
|
Location of station. LOCAL indicates that the station is on the local network. REMOTE indicates that the station is on the remote network.
|
peer/port
|
Peer/port number. If the Loc. field lists a REMOTE station, the peer/port field indicates the peer through which the remote station is reachable.

Description
|
Path
|
CMPC or CMPC+ channel path configured.
|
Dv
|
CMPC or CMPC+ subchannel device configured.
|
TGName
|
TG name configured for the CMPC or CMPC+ subchannel.
|
Dir
|
Identifies this CMPC or CMPC+ subchannel as READ or WRITE.
|
Bfrs
|
On the read subchannel, this is the number of 4 KB-size pages that virtual telecommunications access method (VTAM) has allocated for each Read. This will match the MAXBFRU value configured in the VTAM Transport Resource List (TRL) major node. On the write subchannel, this is the maximum number of 4-KB pages VTAM can write to the CMCC adapter for a single channel I/O. The value will always be 16 for the write subchannel because the Channel Interface Processor (CIP)always allows VTAM to write up to 64 KB per channel I/O.
|
Status
|
State of the CMPC or CMPC+ subchannel. Valid values are:
•Shutdown—CMCC adapter interface for this CMPC or CMPC+ subchannel is shut down. In this state, the Bfrs value is not available and will be displayed as zeros.
•Inactive—CMPC or CMPC+ subchannel is not active.
•XID2 Pending—exchange identification (XID)2 handshaking in progress.
•Active—XID2 exchange completed; CMPC or CMPC+ subchannel is active.
•Active+—XID2 exchange is complete; subchannel is active in High-Performance Data Transfer (HPDT) mode.

Usage Guidelines
The information that is displayed by this command is generally useful for diagnostic tasks performed by technical support personnel only.
Examples
The following is sample output from the show extended channel csna command. Three examples are provided, one for each type of output as specified by the admin, oper, and stats keywords.
The following example displays the configured values for all CSNA devices on interface channel 1/0:
Router# show extended channel 1/0 csna admin
Path Dv maxpiu time-delay length-delay
CSNA C200 60 64000 100 64000
CSNA C200 61 64000 100 64000
CSNA C200 62 64000 100 64000
The following example displays operational data for all CSNA devices configured on interface channel 1/0. The channel interface must be up (no shut) for this information to be displayed.
Router# show extended channel 1/0 csna oper
Path Dv Status SlowDown maxpiu time-delay length-delay
CSNA C200 60 setupComplet off 64000 100 64000
CSNA C200 61 setupComplet off 64000 100 64000
CSNA C200 62 setupComplet off 64000 100 64000
The following example displays CSNA statistics for subchannel path c200, device 60. The channel interface must be up (no shut) for this information to be displayed. If the maxpiu value is reconfigured while the CSNA subchannel is active (setupComplete) then the maxpiu value displayed by the oper keyword is the old, operational value.
Router# show extended channel 1/0 csna c200 60 stats
Blocks Transmitted = 38979079 Received = 38979075
Bytes Transmitted = 79251477K Received = 13554

Description
|
Path
|
Path from the CSNA configuration.
|
Dev
|
Device address from the CSNA configuration.
|
Status
|
State of the CSNA device. One of the following values:
•closed—Subchannel is closed.
•pendingOpen—An Open Subchannel command has been received from virtual telecommunications access method (VTAM).
•open—Subchannel is open.
•pendingSetup—VTAM has queried Channel Interface Processor (CIP) for all configured MAC adapters.
•setupComplete—All internal MAC adapter information has been collected from the CIP. The CSNA subchannel is operational.
•pendingClose—A Close Subchannel command has been received from VTAM.
•unknown—Current state of the CSNA subchannel cannot be determined.
|
SlowDown
|
Status of flow control for the CSNA device.
•off—Subchannel is normal (both CSNA and VTAM are able to send data.
•sent— CSNA has put VTAM into a slow down state for this CSNA subchannel.
•received—VTAM has put the CSNA subchannel into a slow down state.
•both—Both VTAM and the CSNA subchannel are in a slow down state.
•unknown—Current state of flow control on this CSNA subchannel cannot be determined.
|
maxpiu
|
Maximum size of a channel I/O block that the CSNA subchannel can send to the host. This value may differ from the configured maxpiu value if the value is reconfigured while the CSNA subchannel is active (setupComplete).
CSNA blocks Systems Network Architecture (SNA) frames into channel I/O blocks which must not exceed the maxpiu value. A length-delay value less than the maxpiu value can cause the channel I/O blocks to be limited to the lower value.
The maxpiu value may be reconfigured while the subchannel is operational but the new maxpiu value does not take effect until the subchannel is reinitialized (in other words, until the XCA major node is recycled). In this case, the maxpiu value displayed with the admin keyword will be the new, configured value while the maxpiu displayed by the oper keyword will be the old, operational value.
|
time-delay
|
CSNA blocks SNA frames destined for VTAM for time-delay milliseconds from the time the first SNA frame within a channel I/O block is blocked from sending. This can increase the overall throughput of CSNA by minimizing the number of channel I/O operations. However, blocking can induce response time latency of a transaction by up to the time-delay value. If time-delay=0, CSNA ignores length-delay and puts each frame into the channel I/O block for sending to the host. Even with a time-delay=0, CSNA may still block frames while waiting for a previous channel I/O to complete.
|
length-delay
|
CSNA blocks SNA frames destined for VTAM when the current block reaches the length-delay value in size (bytes). This will increase the chance of using larger block sizes for CSNA channel I/O. SNA frames are blocked up to either time-delay milliseconds or until the block reaches the length-delay size, at which time CSNA starts the channel I/O.
The length-delay is ignored if larger than the maxpiu value. It can be used to force CSNA blocking to generate smaller I/O blocks than specified by maxpiu. In general, however, larger blocks result in better channel throughput and efficiency. A value of zero causes the length-delay value to be ignored; blocking is then controlled by the maxpiu and time-delay parameters.
|
Blocks Transmitted
|
Number of channel I/O blocks sent to VTAM from this CSNA subchannel. The Blocks Transmitted value may be higher than the total blocks for the Txd by maxpiu, Txd by time-delay, and Txd by length-delay counters. This is due to NULL blocks (8 bytes each with no data) that CSNA sends. The channel program used for link-state advertisement (LSA) traffic consists of a write/read CCW chain. When VTAM has data for CSNA it sends it with the write CCW. When the chained read CCW is executed CSNA will respond with any pending inbound data. If CSNA has no pending inbound data the read CCW is satisfied with an 8-byte header indicating no data.
|
Blocks Received
|
Number of channel I/O blocks received from VTAM by this CSNA subchannel.
|
Slow downs Sent
|
Number of times CSNA put VTAM into a slowdown (flow control) for this subchannel device.
|
Slow downs Received
|
Number of times VTAM put CSNA into a slowdown (flow control) for this subchannel.
|
Txd by maxpiu
Blocks/Bytes
|
Number of channel I/O blocks and bytes sent to VTAM by this CSNA subchannel because the size of the channel I/O block reached the maxpiu value configured for this subchannel.
|
Txd by time-delay
Blocks/Bytes
|
Number of channel I/O blocks and bytes sent to VTAM by this CSNA subchannel because the blocking time delay configured for this subchannel expired.
|
Txd by length-delay
Blocks/Bytes
|

Table 38 show extended channel ip-stack Field Descriptions
Field
|
Description
|
Alias addresses
|
Virtual IP addresses assigned to the real IP address of an offload device.
|
Forwarding
|
Indication of whether this entity is acting as an IP gateway in respect to the forwarding of datagrams received by, but not addressed to, this entity. IP gateways forward datagrams. IP hosts do not (except those source-routed via the host).
Note that for some managed nodes this object may take on only a subset of the values possible. Accordingly, it is appropriate for an agent to return a "badValue" response if a management station attempts to change this object to an inappropriate value.
|
DefaultTTL
|
The default value inserted into the Time-To-Live field of the IP header of datagrams originated at this entity whenever a TTL value is not supplied by the transport layer protocol.
|
InReceives
|
Total number of input datagrams received from interfaces, including those received in error, for this IP address instance.
|
InHdrErrors
|
Number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, and so on.
|
InAddrErrors
|
Number of input datagrams discarded because the IP address in their IP header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported classes (for example, Class E). For entities that are not IP gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.
|
ForwDatagrams
|
Number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. In entities that do not act as IP Gateways, this counter will include only those packets that were source-routed through this entity, and the source-route option processing was successful.
|
InUnknownProtos
|
Number of locally-addressed datagrams received but discarded because of an unknown or unsupported protocol.
|
InDiscards
|
Number of input IP datagrams for which no problems were encountered to prevent their continued processing, but that were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting reassembly.
|
InDelivers
|
Total number of input datagrams delivered to IP user protocols (including Internet Control Message Protocol (ICMP)).
|
OutRequests
|
Total number of IP datagrams that local IP user-protocols (including ICMP) supplied to IP in requests for sending. Note that this counter does not include any datagrams counted in ipForwDatagrams.
|
OutDiscards
|
Number of output IP datagrams for which no problem was encountered to prevent sending them to their destination, but that were discarded (for example, for lack of buffer space). Note that this counter would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion.
|
OutNoRoutes
|
Number of IP datagrams discarded because no route could be found to send them to their destination. Note that this counter includes any packets counted in ipForwDatagrams that meet this no-route criterion. Note that this includes any datagrams that a host cannot route because all of its default gateways are down.
|
ReasmTimeout
|
Maximum number of seconds that received fragments are held while they are awaiting reassembly at this entity.
|
ReasmReqds
|
Number of IP fragments received that needed to be reassembled at this entity.
|
ReasmOKs
|
Number of IP datagrams reassembled.
|
ReasmFails
|
Number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors, and so on). Note that this is not necessarily a count of discarded IP fragments because some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.
|
FragOKs
|
Number of IP datagrams that have been fragmented at this entity.
|
FragFails
|
Number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, for example, because their Don't Fragment flag was set.
|
FragCreates
|
Number of IP datagram fragments that have been generated as a result of fragmentation at this entity.
|
RoutingDiscards
|
Number of routing entries that were chosen to be discarded even though they are valid. One possible reason for discarding such an entry could be to free buffer space for other routing entries.

show extended channel statistics
To display statistical information about subchannels on the physical interface of a Cisco Mainframe Channel Connection (CMCC) adapter, use the show extended channel statistics command in user EXEC or privileged EXEC mode. This command displays information that is specific to the interface channel devices. The information is generally useful only for diagnostic tasks performed by technical support personnel.
show extended channel slot/port statistics [path [device-address]] [connected]
Syntax Description
slot
|
Slot number.
|
port
|
Port number.
|
path
|
(Optional) Hexadecimal value in the range from 0x0000 to 0xFFFF. This value specifies the data path and consists of two digits for the physical connection (either on the host or on the ESCON Director switch): one digit for the control unit address, and one digit for the channel logical address.
|
device-address
|
(Optional) Hexadecimal value in the range from 0x00 to 0xFE. This value is the unit address associated with the control unit number and path as specified in the host input/output configuration program (IOCP) file.
