116 IBM 9077 SP Switch Router: Get Connected to the SP Switch
• 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.
