CN4093 Application Guide for N/OS 8.2
Consider an example consistent with that used for port‐based PFC configuration
(on page 276):
Table 31.
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 Table
configuration shown in Figure 32 on page
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 284 for more information on DCBX.
This example can be configured using the following commands:
CN4093(config)# cee enable
Note: Turning CEE on will automatically change some 802.1p QoS and 802.3x
