Chapter 7. Configuring the Cisco 3012 InfiniBand to Ethernet gateway 131

After logging into the 4948 with sufficient privileges, execute the commands as shown in

Example 7-2 on the 4948. Items starting with an exclamation mark (!) are for reference or

comment only and are not executed.

Example 7-2 Configure the 4948 to accept untagged packets from the gateway

! Assumes starting from enable mode, enter config mode

7. After the changes have been made to both the Ethernet gateway module and the 4948,

the InfiniBand client at 172.16.225.10 can successfully ping the VLAN 88 default gateway

IP address (172.16.225.250) on the 4948 as demonstrated in Example 7-3.

Example 7-3 InfiniBand host pinging the default gateway

[root@localhost ~]# ping -c 5 172.16.225.250

Tip: Example 7-2 is for a switch running IOS. If the upstream switch is running CatOS,

the configuration would be different, CatOS configuration examples are not included in

this document.
