PVC Establishment/Deletion

Release 2.3 supports SNMP pvc establish and pvc delete from the NMS running CiscoView. The connection MIBs are proprietary. The procedure of how to establish/delete connections is included with CiscoView documentation.

Note CiscoView documentation is available on Cisco Connection Documentation CD-ROM or printed copies can be ordered.

Traffic Management/Accounting Functions:

The following traffic information can be retrieved by a console terminal or an NMS station.

Number of transmitted cells per connection
Number of received cells per connection
Number of transmitted cells per LINF
Number of received cells per LINF - Number of transmitted cells per LINF traffic class (Guaranteed Best Effort---GS/BE)
Number of received cells per LINF/traffic class (GS/BE)

The following performance information can be also retrieved by a console terminal and/or a NMS station:

Number of UPC violation cells per connection
Number of HEC errored cells per LINF
Number of Misdelivered cells per LINF

All these parameters are implemented by 32-bit roll-over counters. These counters will not be reset after the retrieval but can be reset via a CLI command (clear tcounter).

Related CLI commands

The following are related CLI commands:

show traffic

The show traffic command displays the line number and numbers of received (input) cells, transmitted (output) cells, misdelivered cells, Header Error Check (HEC) errored cells, and buffer overflow cells for each line. The contents of software-controlled, 32-bit counters are read out. (The counters can be reset with the clear tcounter command.)

Format:

A100> show traffic P1

P1 Line number (0-15). Traffic and performance data of the specified LINF is displayed.

Command example:

A100> show traffic 8

Diagnostics Functions:

Release 2.3 software supports the diagnostic capabilities for the following hardware components:

CPU/Processor card
Mother board (XATOM switching fabric)
Gateway PAD card
Line interface (LINF) card

While executing the diagnostic process, the corresponding online service of the hardware components is suspended. However, any individual LINF card can be checked without affecting the online service of the other LINF cards.

diagnosis

The diagnosis command displays diagnostic information.

Format:

A100> diagnosis P1 P2

Format explanation:

P1: One of the following:

cpu (CPU board diagnosis)

switch (XATOM/Mother board diagnosis)

gateway (Gateway PAD card diagnosis)

line (line interface card - LINF diagnosis)

all (Entire system diagnosis)

P2: Line number (specified when P1 = line)

The result of any diagnostics process is displayed on a console terminal or can be retrieved by entering the show alarm command.

Soft Reset

System soft reset from a console terminal and/or NMS station is supported. This CLI command is executed in an interactive manner.

Format:

reset

Command example:

A100# reset         
Are you sure [Y or N]?

New and Improved CLI Commands

show pvc

The show pvc line and show pvc detail commands are combined into a single command. You can specify a line number, line number and VPI, or a line number and VPI and VCI. If only a line number is specified, all the connections on the specified LINF are displayed. If a line number and VPI are specified, all the connections with the specified VPI on the specified LINF are displayed.

Format:

A100> show pvc P1 (P2 (P3))

Format explanation:

P1: Line number (0-15)

P2: VPI (0-4095). If P2 and P3 are omitted, all PVCs on the LINF specified by P1 are be displayed.

P3: VCI (0-4095). If P3 is omitted, all PVCs with the specified VPI established on the line specified by P1 are displayed.

show svc

The display of the show svc command is improved.

Format:

write erase (configuration erase)

The write erase command allows the administrator to completely erase any configuration data that may exist in the Flash memory and is only available in the privileged mode and executed in an interactive manner. The write erase command allows you to erase the entire configuration to start over.

Format:

A100# write erase

Command example:

A100# write erase        
Are you sure [Y or N]?

save

The display output of the save command is modified as follows:

Command example:

A100# save        
Please do NOT push reset button until the "save" is complete
#######[OK]

P6 through P8 are for DS3/E3 LINF cards only and can be ignored for the other (PHY) types of LINF cards.

Flash Memory Access Protection

Release 2.3 software can recover from the reset button being pushed during the save operation. If the reset button is pushed during the save operation, the following message will be displayed on the NMS:

The configuration data was corrupted by pushing the reset button before the save is 
complete!.

If your get this message, you need to reboot the software again using the initialize mode (i.e., set boot initialize because the configuration data stored in Flash memory was corrupted).
