Chapter 20 Troubleshooting IP Storage Services IP Issues Send documentation comments to [email protected] • debug ips error • debug ips islb [config | config-detail | flow | flow-detail } • debug ips islb cfs error • debug ips islb cfs [config | config-detail | flow | flow-detail } • debug ips islb vrrp error • debug ips islb vrrp [flow | flow-detail ] IP Issues If you suspect that all or part of your IP connection has failed, you can verify that by performing one or more of the procedures in this section. Using these procedures, you can verify connectivity for IEEE 802.1Q, EtherChannel, and VRRP for iSCSI. This section includes the following topics: • Verifying Basic Connectivity, page 20-5 • Verification of Switch Connectivity, page 20-7 • Verification of Static IP Routing, page 20-8 • Cannot Assign IP Address to an Interface, page 20-9 Note If you configure secondary VRRP IPv6 addresses on an IPFC VSAN interface, before a downgrading to a release prior to Cisco Release 3.0(1), you must remove the secondary VRRP IPv6 addresses. This is required only when you configure IPv6 addresses. Verifying Basic Connectivity Use the procedures in this section to verify that you have IP connectivity. Verifying Basic Connectivity Using Device Manager To verify basic connectivity using Device Manager, follow these steps: Step 1 Choose IP > Routes to verify the static route to the remote device. Step 2 Choose Interface > Ethernet and iSCSI to verify that the Gigabit Ethernet interface is up. Verifying Basic Connectivity Using the CLI To verify basic connectivity using the CLI, follow these steps: Step 1 Use the ping or the ping ipv6 command to perform a basic check of host reachability and network connectivity. switch# ping 11.18.185.121 PING 11.18.185.121 (172.18.185.121): 56 data bytes 64 bytes from 11.18.185.121: icmp_seq=0 ttl=128 time=0.3 ms OL-9285-05 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x 20-5
