Export Connection Error Log

When you select the Export Connection Error Log option, SANsurfer iSCSI HBA CLI prompts you for a file name with which to save the log of connection errors. Enter a file name and then press ENTER.

Display Neighbor Cache (IPv6)

(CLI Option -nc)

Select the Display Neighbor Cache (IPv6) option to view the IPv6 neighbor cache. Similar to the ARP table in IPv4, the neighbor cache is a set of entries about individual neighbors to which traffic has been sent recently. Entries contain such information as its link-layer address, a flag indicating whether the neighbor is a router or a host, a pointer to any queued packets waiting for address resolution to complete, and so forth.

Display Destination Cache (IPv6)

(CLI Option -dc)

Select the Display Destination Cache (IPv6) option to view the IPv6 destination cache containing the IP address, next-hop IP address, and path MTU information about both local and remote destinations. For multicast and on-link unicast destinations, the next-hop IP address always matches the destination IP address. For unicast destinations that are off-link, the next hop IP address is the IP address of the router.

Display Default Router List (IPv6)

(CLI Option -dr)

Select the Display Default Router List (IPv6) option to view the IPv6 default router list, which includes both the active default router and a short list of other routers that advertised themselves as being able to act as a default router. The active default router always appears first in the list.

Display Local Prefix List (IPv6)

(CLI Option -lp)

Select the Display Local Prefix List (IPv6) to view the IPv6 local-prefix list created by the HBA from prefix information in router advertisements. The HBA can reach destination IP addresses containing these prefixes directly, without going through an intermediate router.

The following shows how a typical list may look:

Local Prefix Entry number 0

Preferred Lifetime <secs> - 604669

Valid Lifetime <secs> = 2591869

Prefix = 3ffe:4032:1077:2006
Update time <from FW boot> =				514 seconds,	0	milliseconds
Update	time	<from FW	boot> =	8 mins 34 secs		0 millisecs
Update	time	= Mon	Apr 23 17:17:30 2007
