• Can't access the CT900 network Switch
  
• Can't login to a ShMM
• Unable to telnet to Switch
  
• Unable to telnet to the Shelf Manager
  

• Verify Physical Cable Connections
  

• Switch Network Management Port

Each Switch Board comprises 2 physical Switch Units. Each Switch Unit has their own management interface which is accessible through the serial port or through a network interface known as the Serviceport. For the Netra CP3140 1Gbps Switch and the Netra CP3240 10Gbps switch, both the Switch Unit Serviceports are connected to a common Network Management Port on the front panel and on the optional Rear Transmission Module (RTM and ARTM respectively).

Refer to attachments cp3140_front_panel.gif , CP3140_RTM.gif and cp3240_front_panel.gif at the bottom of this document for network port locations. Check the network management physical ports on both switches for a good cable connection.

• Shelf Management Module (ShMM) Network connectivity

The ShMM can be accessed via the Base Network through the Switch Blade using the midplane connection. External access is achieved by connecting to any Base Network Port on either Switch. Check the physical ports on both switches for a good cable connection.

• Verify Link Status

Having checked that the cable is plugged in, the status of the link should be checked.

The switch network management ports do not have link connection LEDs. It will be necessary to check the link status at the other end of the cable on the device it is plugged into.

For the connection to be used by the ShMM, verify that the external cable port is showing an active link. Connection into the CP3140 can be checked by looking at the LEDs, see <Document: 1019516.1> If local access is not convenient, remote interrogation of the switch ports will show the status of the link. Connect to the switch through the Base Network serial port. Any problems refer to < Document: 1019404.1 > . Log in as the admin user and enable superuser mode. Issue the show port all command and confirm the link is working.

Example:

(v-ct900b-sw-a-b-gmp02) #show port all

0/18          Enable  Auto                  Down   Enable  Enable
0/19          Enable  Auto                  Down   Enable  Enable
0/20          Enable  Auto       100 Full   Up     Enable  Enable
0/21          Enable  Auto                  Down   Enable  Enable
0/22          Enable  Auto                  Down   Enable  Enable
0/23          Enable  Auto                  Down   Enable  Enable
0/24          Enable  Auto                  Down   Enable  Enable  

In this example Port 20 is the external port and is showing the link to be up and running at 100Mbps. The other ports with link up status are all internal connections within the shelf.

• Verify Network Interface Configuration

Initial setup of the network connection to the Switches and Shelf Management Modules is carried out through the appropriate serial ports. Please refer to <Document: 1019404.1> for serial connection problems.

• Check the ShMM eth 0 (and eth 1 configuration if net-connect is being used)

Details can be found in <Document: 1019501.1> How to verify the network configuration for the Shelf Management Module (ShMM) on the Sun Netra CT900 Platform.

• Check the Switch Network Management Port Configuration

Log into the switch through the serial port as user: admin and enable superuser.

Verify the IP parameters using the show serviceport command

You will need to do this for both the Base and Extended Networks for both Switch Blades.

Example:

(v-ct900b-sw-a-b-gmp02) #show serviceport
IP Address..................................... 129.156.205.111
Subnet Mask.................................... 255.255.252.0
Default Gateway................................ 129.156.204.1
ServPort Configured Protocol Current........... None
Burned In MAC Address.......................... 00:20:13:F0:BE:18

Note: in this example the subnet is not a standard class C subnet

If the settings do not match the expected configuration, use the serviceport command to set the correct values.

Example:

(v-ct900b-sw-a-b-gmp02) #serviceport ip 129.156.205.111 255.255.252.0 

In this example the IP address and netmask have been set. The default gateway is optional and can be set by adding the address as an additional parameter at the end of the command string.
