IBM 9077 manual Some maint Commands for the ATM OC-3c Media Card, Vpi/Vci

•Interface section

Define the traffic shaping profile for the logical interface to which the media card’s PVCs are assigned.

•PVC section

Specify characteristics for each PVC, including:

•Assigned logical interface name

•VPI/VCI

•Protocol supported

•Whether AAL is used

•Assigned traffic shaping profile (only if it would be different from the profile given previously to the logical interface in the Interface section)

Templates of these configuration files are in GRF Reference Guide 1.4, GA22-7367; traffic shaping is discussed in detail in GRF Configuration Guide 1.4, GA22-7366.

Hint: Use gratm -n ga0<slot_the_ATM_card_is_in> to check for any errors in /etc/gratm.conf.

The actual data for configurations we tested will be presented in Section 5.1.3, “SP Switch - ATM Connection” on page 167 and Section 7.1, “ATM OC-3c Backbone Connection” on page 209, respectively.

4.2.7 Some maint Commands for the ATM OC-3c Media Card

The maint commands display a range of information about the media card. The ATM OC-3c card has individual processors for the transmit and receive sides, and two sets of maint commands. One set covers the receive (RX) side and includes some commands applicable to the card overall. The second set covers the transmit (TX) side. Transmit side counterparts of receive side commands use the same number but are 100-based. For example, the receive side maint 8 is transmit side maint 108.

To use maint, follow these steps:

•First, switch to the maint prompt with the grrmb command. A new prompt,

GR 66>, will appear.

•Then change the prompt port to the ATM media card you are working with. For example, if you are working with a card in slot 3, enter GR 66> port 3.
