notes provided with the Gate 3 load.

• Chapter 1 provides an overview of the document.

• Chapter 2 lists all the problem reports resolved in this release. Also

included is a description of new VMI commands and their usage to

facilitate debugging of ’OAM Payload Type Cells’. This command was

added in VSS1.1 ER Number 7.

Vector Software Resolved Issues

The following is the list of items which have been resolved in this (No. 8) 1.1 Post Gate 3

release.

Priority Serv. No Request Title

major 10139980 Unable to time the Vector Access Shelf using a DS3 connection

This SR resolves the problem of the DS3 Network Module not providing stable line timing when

the timing source was imported from the switch backplane (i.e. via another netmod). This

resulted in the DS3 netmod defaulting to the on-board crystal for its timing source causing line

timing slippages to far end equipment connected to it.

New VMI Commands

Under the ’operation’ level on the VMI, a new submenu, ’oampt’, has been added that provides

commands to perform debugging on ’OAM Payload Type Cells’ received by the Switch Control

Processor (SCP).

The four commands under the ’oampt’ submenu are:

monitor - Enable/Disable oamPT cell VP/VC monitoring

suspectcells - Display total oamPT cells received while last in FIFO

totalcells - Display total oamPT cells received

resetcounters - Reset the oamPT cell counters

Use of New VMI Commands

monitor - usage: monitor [(enable | disable)]

When enabled allows the user to monitor the connections over which

oamPT (OAM Payload Type) cells are being received. The default option

after rebooting the switch is disabled.

Magellan Vector 1.1 Release Notes

At most a hundred (100) entries will be stored in every 10 seconds interval

and displayed as follows on the debug port as well as the serial port.

asxd: INFO: oamPT cells found in last 10 seconds: Fri Nov 7 12:48:48 1997

asxd: INFO: ( 1) oamPT cell found on Output Port: CTL, VP 0, VC 34

asxd: INFO: ( 2) oamPT cell found on Output Port: CTL, VP 0, VC 34

Using the conﬁguration vcc show commands as below, the connection

corresponding to the INFO (1) and (2) above for ’Output Port: CTL, VP 0,

VC 34’ is found to be ’1A1 0 5 1CTL 0 34’.

Therefore, with this information it can be concluded that the OAM Payload

Type cells are being received from Input Port 1A1, VPI 0, VCI 5 which are

being sent to the Control Port (i.e. the SCP) on VPI 0, VCI 34.

localhost::conﬁguration vcc> show

Input Output

Port VPI VCI Port VPI VCI UPC Protocol

1A1 0 5 1CTL 0 34 uni30

1A1 0 14 1CTL 0 33 0 spans

1A1 0 15 1CTL 0 32 spans

1A1 0 16 1CTL 0 80 uni30

suspectcells - usage: suspectcells

This gives the count of OAM Payload Type cells received which causing

the Control Port to block and cause all the SPANS and UNI signalling

channels to remain in ’down’ state.

localhost::operation oampt> suspectcells

Total:10 Delta:2

The Total counts gives the total cells of this type received and the Delta

gives the count of such cells received since the last time this command was

used.

totalcells - usage: totalcells

This gives the count of all OAM Payload Type cells received and

successfully discarded. This count includes the count for ’suspectcells’

localhost::operation oampt> totalcells

Total:5968 Delta:4513

The Total counts gives the total cells of all OAM Payload Type received and

the Delta gives the count of such cells received since the last time this

command was used.

resetcounters - usage: resetcounters [(suspectcells)|(totalcells)|(all)]

Chapter 2 Vector Software Resolved Issues 5

Magellan Vector 1.1 Release Notes

This command resets the Total and Delta values of the selected counter to

zero (0). The ’all’ resets both counters.
