Description
This document describes how to verify the network connections required for management of Sun[TM] Netra CT900

Symptoms

Can't access CT900 Switch Blade (CP3140/3240)
Can't login to a ShMM
Unable to ping/telnet to Switch Blade
Unable to ping/telnet to Shelf Manager Modules (ShMM)

Purpose and Scope
This document will cover the physical network connection and basic setup of the management interfaces for Sun Netra CT900 switches and ShMM for purpose of mangement of the shelf.
It does not cover specific connection to Server Nodes nor wider network issues.

Steps to Follow
Verifying correct network connectivity involves checking

1. Physical cable connections
2. Link status
3. Network interface configuration

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 serial port or through a network interface known as Serviceport. For Netra CP3140 1Gbps Switch and Netra CP3240 10Gbps switch, both Switch Unit Serviceports are connected to a common Network Management Port on front panel and on optional Rear Transmission Module (RTM and ARTM respectively).

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

Shelf Management Module (ShMM) Network connectivity

The ShMM can be accessed via Base fabric through Switch Blade using midplane connection. External access is achieved by connecting to any Base fabric Port on either Switch if switch blades are under redundant configuration (i.e. 0/2 port of BASE fabric is up and running --- see the following for details on how to check 0/2 port) or access shm1 (top ShMM) via switch blade 7 and shm2 (bottom) via switch blade 8. Check 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 cable on the device it is plugged into.

For connection to be used by ShMM, verify that external cable port is showing an active link. Connection into 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 switch blade through the Base fabric serial port. Any problems refer to < Document: 1019404.1 >. Log in as the "admin" and "enable" to enter exclusive mode. Issue show port all command and confirm the link is working.

Example:

(v-ct900b-sw-a-b-gmp02) #show port all
Admin   Physical   Physical   Link   Link    LACP
Intf   Type    Mode    Mode       Status   Status  Trap    Mode
------ ------ ------- ---------- ---------- ------ ------- -------
0/1           Enable  Auto       100 Full   Up     Enable  Enable
0/2           Enable  Auto       1000 Full  Up     Enable  Enable
0/3           Disable Auto                  Down   Enable  Enable
0/4           Disable Auto                  Down   Enable  Enable
0/5           Enable  Auto       1000 Full  Up     Enable  Enable
0/6           Disable Auto                  Down   Enable  Enable
0/7           Disable Auto                  Down   Enable  Enable
0/8           Disable Auto                  Down   Enable  Enable
0/9           Enable  Auto       1000 Full  Up     Enable  Enable
0/10          Disable Auto                  Down   Enable  Enable
0/11          Enable  Auto       1000 Full  Up     Enable  Enable
0/12          Enable  Auto       1000 Full  Up     Enable  Enable
0/13          Enable  Auto       1000 Full  Up     Enable  Enable
0/14          Enable  Auto       1000 Full  Up     Enable  Enable
0/15          Disable Auto                  Down   Enable  Enable
0/16          Disable Auto                  Down   Enable  Enable
0/17          Enable  Auto                  Down   Enable  Enable
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

Port 0/1 to 0/16 are all internal and 0/17 is not used; port 0/18 to 0/24 are external links. In this example, Port 20 is the external port showing link to be up and running at 100Mbps.

Verify Network Interface Configuration

Initial setup of network connection of Switch Blade and ShMM 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 switch blade via serial port as user: "admin" and "enable" to enter exclusive mode

Verify the IP parameters using show serviceport command

You will need to do this for both Base and Extended fabrics 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 expected configuration, use 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.
