Users Guide

• VLAN membership:

• The Aggregator auto-congures the VLANs which handle FCoE trac. You can recongure VLAN membership on a port (vlan

tagged command).

• Each FIP snooping port is auto-congured to operate in Hybrid mode so that it accepts both tagged and untagged VLAN frames.

• Tagged VLAN membership is auto-congured on each FIP snooping port that sends and receives FCoE trac and has links with an

FCF, ENode server or another FIP snooping bridge.

• The default VLAN membership of the port should continue to operate with untagged frames. FIP snooping is not supported on a

port that is congured for non-default untagged VLAN membership.

FIP Snooping Restrictions

The following restrictions apply to FIP snooping on an Aggregator:

• The maximum number of FCoE VLANs supported on the Aggregator is eight.

• The maximum number of FIP snooping sessions supported per ENode server is 32. To increase the maximum number of sessions to 64,

use the fip-snooping max-sessions-per-enodemac command. This is congurable only in PMUX mode.

• In a full FCoE N port ID virtualization (NPIV) conguration, 16 sessions (one FLOGI + 15 NPIV sessions) are supported per ENode. In an

FCoE NPV confguration, only one session is supported per ENode.

• The maximum number of FCFs supported per FIP snooping-enabled VLAN is 12.

• Links to other FIP snooping bridges on a FIP snooping-enabled port (bridge-to-bridge links) are not supported on the Aggregator.

Conguring FIP Snooping

FIP snooping is auto-congured on an Aggregator in standalone mode. You can display information on FIP snooping operation and statistics

by entering show commands. You can enable FIP snooping globally on all FCoE VLANs on a switch or on an individual FCoE VLAN.

By default, FIP snooping is disabled.

To enable FCoE transit on the switch and congure the FCoE transit parameters on ports, follow these steps.

1 Enable the FCoE transit feature on a switch.

CONFIGURATION mode.

feature fip-snooping

2 Enable FIP snooping on all VLANs or on a specied VLAN.

CONFIGURATION mode or VLAN INTERFACE mode.

fip-snooping enable

By default, FIP snooping is disabled on all VLANs.

3 Congure the FC-MAP value used by FIP snooping on all VLANs.

CONFIGURATION VLAN or INTERFACE mode

fip-snooping fc-map fc-map-value

The default is 0x0EFC00.

The valid values are from 0EFC00 to 0EFCFF.

4 Enter interface conguration mode to congure the port for FIP snooping links.

CONFIGURATION mode

interface port-type slot/port

By default, a port is congured for bridge-to-ENode links.

5 Congure the port for bridge-to-FCF links.

INTERFACE or CONFIGURATION mode
