channel 6 or 7. Verify that the multicast channel has the frame class
priority set to the frame class of the expected traffic.
VC Priorities Pressing <Enter> while
VC Priorities is selected, displays:
The numbers displayed show the priorities assigned to each of the
switch’s virtual channels. Positions 1 and 2, starting at the left of the
display, are fixed and displays 0 or 1.
The first position, a ‘0’, shows and indicates that this virtual channel,
assigned to handle internal switch traffic, has the highest priority.
This priority value cannot be changed by the user.
The second position, indicated with a 1, shows the priority assigned
by the virtual channel link control as described in the VC Link Ctl on
page 3-15.
The third through eighth positions can have only a 2 or a 3 indicating
that the channel gives priority to either Class 2 frame traffic or to
Class 3 frame traffic.
Frame Collection Pressing <Enter> while
Frame Collection is selected, displays:
This command specifies two frame collection methods, bundle and
piling. Using bundling, frames are separated in different queues
based on source/destination pairs. Using piling, frames are
accumulated per destination AL_PA If NL_Ports can handle multiple
frames in a loop. Additionally, piling can minimize loop traffic by
reducing overhead and increases the loop efficiency.
To set, press <Tab/Esc> for Bundle or <Enter> for Piling.
