Viewing the IPv6 Neighbor Cache Log
The IPv6 Neighbor Cache contains the IP address, MAC address, and other
information about devices on the local link. This cache is similar to the IPv4 ARP
cache (see
“Viewing the ARP Log” on page 6-6
). It provides mapping between
unicast IP addresses and their associated MAC addresses.
To view the neighbor cache log:
1.
On the SANsurfer iSCSI HBA Manager main window HBA tree, select the
HBA port.
2.
Click the
Diagnostics
tab to bring the Diagnostics page to the front.
The top portion of the Diagnostics page contains the HBA port-identifying
information; for details, see
“General Information for the HBA Port” on
page 6-2
.
3.
On the Diagnostics page, click the
Logs
tab.
The Logs page opens within the Diagnostics page (see
Figure 6-4 on page

Last Update Time
The date-time stamp of the last destination cache
entry. The date-time stamp is in 12 hour format.
Destination IP
The destination IP address of an IPv6 iSCSI target.
Next Hop IP
The IPv6 IP address of the next hop from the iSCSI
HBA port. If the iSCSI target is on the local subnet,
then this address is the same as the destination IP
address. If the iSCSI target is not on the local subnet,
then this address is the first router/gateway address in
the path to the iSCSI target.
Path MTU
The path MTU between the HBA port and the iSCSI
target. The value is generally zero, except when an
oversized ICMPv6 packet message is received.
Flags
Local valid entry=0x5; remote valid entry=0x1.
