CN4093 Application Guide for N/OS 8.3
Consider an example consistent with that used for port-based PFC configuration
(on page 294):
Table 30.
ETS Configuration
Priority Usage
0 LAN (best effort delivery)
1 LAN (best effort delivery)
2 LAN (best effort delivery)
3 SAN (Fibre Channel over Ethernet, with PFC)
4 Business Critical LAN (lossless Ethernet, with
PFC)
5 Latency-sensitive LAN
6 Latency-sensitive LAN
7 Network Management (strict)
The example shown in
configuration shown in
LAN traffic (802.1p priority 5 through 6) are moved from priority group 2 to
priority group 3. This leaves Business Critical LAN traffic (802.1p priority 4) in
priority group 2 by itself. Also, a new group for network management traffic has
been assigned. Finally, the bandwidth allocation for priority groups 1, 2, and 3 are
revised.
Note: DCBX may be configured to permit sharing or learning PFC configuration
with or from external devices. This example assumes that PFC configuration is
being performed manually. See
page 302 for more information on DCBX.
Table 30 is only slightly different than the default
