CN4093 Application Guide for N/OS 8.4
Port Aggregation
Enterprise NOS 8.4 supports port aggregation for FCoE connections. Link
Aggregation (LAGs) can be used for separate FCoE traffic, or for Ethernet and
FCoE traffic. The ports can be grouped as static LAGS or dynamic LACP LAGs.
Normal aggregation operations such as creating or enabling a LAG, and adding or
removing member ports can be performed. When a port is added to a LAG, FCFs
previously detected on the port will be deleted. The deleted FCF may be relearned
later. However, this may cause flickering in the network traffic. It is recommended
that any LAG changes are made prior to live FCoE traffic.
Priority ‐ based Flow Control (PFC) and Data Center Bridging (DCBX) are
configured on a per ‐ port basis. Each port in a LAG must have the same ETS, PFC
and DCBX configuration. When a port ceases to be a LAG member, its
configuration does not change.
Note:
If the ports chosen to be part of a certain LAG do not have the same PFC,
ETS or DCBX configurations, the switch will display an error.
Global FIP Snooping Settings
By default, the FIP snooping feature is turned off for the CN4093. The following
commands are used to turn the feature on or off:
Note:
FIP snooping requires CEE to be turned on (see “Turning CEE On or Off” on
page 302 ).
When FIP snooping is on, port participation may be configured on a port ‐ by ‐ port
basis (see below).
When FIP snooping is off, all FCoE ‐ related ACLs generated by the feature are
removed from all switch ports.
FIP Snooping for Specific Ports
When FIP snooping is globally turned on, ports may be individually configured for
participation in FIP snooping and automatic ACL generation. By default, FIP
snooping is enabled for each port. To change the setting for any specific port, use
the following CLI commands:
When FIP snooping is enabled on a port, FCoE ‐ related ACLs will be automatically
configured.
When FIP snooping is disabled on a port, all FCoE ‐ related ACLs on the port are
removed, and the switch will enforce no FCoE ‐ related rules for traffic on the port.
Note:
FIP Snooping and IPv6 ACLs are not support simultaneously on the same
ports. To use FIP snooping, remove IPv6 ACLs from the port.
