1.3 VRTX 10GbE Switch Module (R1-2210) The VTRX 10GbE Switch Module, model R1-2210, is a layer 2 switch that supports speeds up to 10 Gbps. Both the switch GUI and CLI provide access for configuring the switch. The OOB management IP must be on a different IP subnet than those defined on all other switch interfaces (port, VLAN). Blade servers are connected to internal (te 1/1 – te 4/4) ports. The internal ports communicate together allowing for east-west traffic.

3 Connectivity, troubleshooting and product tips for VRTX Ethernet switches using CLI The following sections contain steps to enable or troubleshoot basic connectivity. Most of these steps are CLI-only. Therefore, these sections focus on this method. 3.1 Prerequisites The following procedures use the switch CLI, CMC CLI and blade server operating system (OS) to troubleshoot connectivity between the VRTX switch and the VRTX blade servers.
3.3 Basic connectivity and management from the switch CLI The following sections contain the basic commands to enable connectivity and management through the switch CLI. 3.3.1 Check the status of all interfaces Log in to the switch CLI and run show interface status to see all the interfaces and their current status.
3.3.2 Check a specific port status from the switch CLI Log in to the switch CLI and run show interface status gi s/p (where s= slot, p=port). Example for a Down port: VRTX-switch#show interface status gi1/1 Port -------gi1/1 Type -----1G Flow Duplex Speed Neg ctrl ---------- ----- -------- Link State ------Down Back Pressure --------- Mdix Mode ------- Example for an Up port: VRTX-switch#show interface status gi1/1 Port -------gi1/1 3.3.
3.3.5 Reload a switch from the switch CLI Log in to the switch CLI and type the following command to reload or reboot the switch: VRTX-switch#reload VRTX-switch#This command will reset the whole system and disconnect your current session. Do you want to continue? (Y/N)[N]Y Note: Be sure to save running-config from section 3.3.4 before reloading. 3.3.6 Assign an IP address to switch VLAN 1 from the switch CLI Log in to the switch CLI and configure the VLAN 1 IP address.
3.4 Troubleshooting and connectivity tips This section covers general and connectivity troubleshooting. While it may not address all problems, it should cover the most common problems. 3.4.1 Password recovery and setting the switch to factory defaults If device management access uses the switch’s local user database and loses the password, there are two procedures to recover the password: through the CMC and through the switch’s Startup Menu.
4. Update password. Note: If the service password-recovery command is enabled, complete configuration is retained. If the service password-recovery command is disabled, the switch is restored to the default configuration and uses default settings and default user/password on the next boot. 3.4.2 Troubleshooting flow chart The troubleshooting flow chart shown in Figure 17 and Figure 18 provides server I/O connectivity troubleshooting.
Troubleshooting Flow Chart (Part 2) Back to beginning of flow chart Continued from first half of chart Is the MAC address for NIC present on the switch NO - Assign IP address to the NIC Port in the server OS - Verify Firewall on the blade server OS allows ping traffic to be received YES - Assign an IP address on the same subnet as the NIC to switch VLAN 1 Try the following steps to re-initialize ports and attempt successful ping shut/no shut switch port Disable/enable NIC port in OS Restart bl
3.4.3 Additional explanation of troubleshooting steps 3.4.3.1 How to Confirm the NIC is present on blade server Enter the LifeCycle Controller during Post or check the blade server information from the CMC. 1. During blade server POST, enter LifeCycle Controller mode (F10) and confirm NIC is listed in inventory If it is not listed: a. Verify installation of NIC in blade server. b. Install NIC if necessary. If it is listed: a. Restart or reseat blade server. b.
a. Enter config mode from the switch CLI and execute shut/no shut on the switch port. b. Verify switch port link state. If up, re-initialization of the link was required to bring port up. c. If port is still down, follow these steps to re-initialize the ports to get a link “up” state. i. Disable/Enable NIC port in OS. ii. Restart blade server. iii. Reseat blade server. iv. Save running-config and reload switch. v. Set switch to factory default configuration. vi. Save running-config and reseat switch. vii.
b. From switch CLI run command show mac address-table. Review switch MAC address list for NIC MAC addresses (can also associate to switch port ID listed with each MAC address). Note: More than one MAC can be present per NIC port if NIC is a CNA 4. Confirm ping traffic passes if NIC MAC addresses are present From the switch CLI – enter in the appropriate address for nnn.nnn.nnn.nnn with nnn.nnn.nnn.nnn being the appropriate IP address on the infrastructure subnet. VRTX-switch#ping nnn.nnn.nnn.
i. o 28 Log in to the switch CLI and go to interface configuration mode. ii. Identify the switch port you want to configure. iii. Enter the appropriate shut/no shut command. iv. Contact tech support, noting defective ports (i.e., if ports 1/14 did not connect properly, and ports 2/1-4 do, switch is defective for ports 1/1-4). If NIC MAC addresses are still not present after slot move, repeat previous steps. If these steps fail, the switch as a whole may be failing: a. Shut/no shut switch port. b.
