Caveats
Symptom: When a SAN port channel is created, the following syslog message is displayed:
2008 May 20 06:09:13 switch %PORT_CHANNEL-3-MSG_SEND_FAILURE: failed to send
MAP_PARAM_FROM_CHANNEL to sap 45: Broken pipe"
There is no functionality loss and this message can be ignored.
Workaround: None.
• CSCso01268

2005 Jan 1 00:08:23 switch %KERN-4-SYSTEM_MSG: SI-VDC map entry <0, 0x0> does not
exist! - kernel"

Symptom: Enhanced Inter Switch Link (EISL) encapsulation is not supported on a Fibre Channel
SPAN destination port. When EISL encapsulation is configured on the SPAN destination (SD) port,
a VFT header is added to the packets going out of the SD port. The VFT header has VSAN
information that helps distinguish traffic for various VSANs. This applies to any Fibre Channel
SPAN source. By default, EISL encap is not added and packets are sent out without a VFT header,
and independent of the type of SPAN source port. For a Cisco Nexus 5000 Series switch, the
switchport encap EISL command does not have any effect.
Workaround: Use the Ethernet SPAN destination port to SPAN Fibre Channel traffic. FCoE packets
going out of the Ethernet SPAN destination port contain VSAN information in the Ethernet VLAN
tag.
