Network port in-band connectivity

Procedure 5-4.5: Network port in-band connectivity

Overview

Use this procedure to configure the network ports for in-band connectivity.

The network interface is the logical interface used for in-band connectivity with the switch through any of the switch's faceplate or shelf Ethernet ports. The configuration parameters associated with the switch's network interface do not affect the configuration of the front panel ports through which traffic is switched or routed.

To access the switch over the in-band network you must first configure it with IP information (IP address, subnet mask, and default gateway).

You can configure the IP information using any of the following:

Bootp
DHCP
Manually through the MGMT LAN port or the EIA-232 console port.

Once you have established in-band connectivity, you can change the IP information using any of the following:

Terminal interface via the EIA-232 port or MGMT LAN port.
Terminal interface via telnet.
SNMP-based management.
Web-based management.

For related CLI command procedures, refer to the following in Chapter 2, Getting started:

Step


1	Login to the VLNC4x/VLNC6x.
2	From the Navigation menu, select `System → Configuration → Network Connectivity`. Equivalent CLI commands: See Related information. Result: The Network Connectivity Configuration window displays the current configuration.
3	Select the Network Configuration Protocol to be used for configuration. If `None` is selected, you must configure network information for the switch manually. If `Bootp` is selected, the switch periodically sends requests to a BootP server until a response is received. If `DHCP` is selected, the switch periodically sends requests to a DHCP server until a response is received.
4	If you are configuring the network ports manually (Network Configuration Protocol = `None`), proceed to Step 7. Otherwise, continue to the next Step.
5	If you use DHCP/BootP to configure the network ports, you must configure the DHCP/BootP server with the following information: Unique IP address for the switch. Subnet mask for the LAN. Gateway IP address of the default router, if the switch is a node outside the IP range of the LAN. MAC address of the VLNC4x/VLNC6x.
6	If the Bootp or DHCP protocol is selected for configuration, connect the switch to the network and click Submit at the bottom of the screen. After the VLNC4x/VLNC6x is connected to the network, it periodically sends requests to a BootP/DHCP server until a response is received. Result: The VLNC4x/VLNC6x is configured with the information from the DHCP/BootP server.
7	If Network Configuration Protocol is `None`, enter IP address, subnet mask, gateway and other parameters, as required. IP Address - IPv4 Address Range. Subnet Mask - Range: 0-255.0-255.0-255.0-255. Default Gateway - IPv4 Address Range.
8	Click Submit at the bottom of the screen to execute the commands. End of steps

Network port parameters

Parameter	Description	CLI command
IP Address	IP address for the network port	`network parms <ipaddr>`
Subnet Mask	This is the subnet mask for the network port	`network parms <netmask>`
Default Gateway	This is the gateway for the network port	`network parms <gateway>`
Burned In MAC Address	The burned in MAC address used for in-band connectivity. Read from EEPROM.	`show network`
Locally Administered MAC Address	This command sets the locally administered MAC address for the VLNC40 only. The following rules apply: Bit 6 of byte 0, called the U/L bit, indicates whether the address is universally administered (b'0') or locally administered (b'1'). Bit 7 of byte 0, called the I/G bit, indicates whether the destination address is an individual address (b'0') or a group address (b'1'). A locally administered address must have bit 6 ON (b'1') and bit 7 OFF (b'0'). For example, the second character of the twelve character macaddr must be 2, 6, A, or E.	`network mac-address <mac-addr>`
MAC Address Type	Specify whether the burned-in or the locally administered MAC address should be used for in-band connectivity for the VLNC40 only. The factory default is to use the burned-in MAC address. Values are: `Burned In` or `Locally Administered`.	`network mac-type {local \| burnedin}`
Network Configuration Protocol Current	Specifies what the switch should do following power-up: transmit a `Bootp` request, transmit a `DHCP` request, or do nothing (`None`). The factory default is `None`.	`network protocol {none \| bootp \| dhcp}`
Management VLAN ID	The Management VLAN on the circuit pack. Valid values: an integer in the range of 1 to 4094. The default value is 1.	`network mgmt_vlan <vlanid>`
Management Priority	The priority of the Management VLAN on the pack. Valid values: an integer in the range of 0 to 7. The default value is 0.	`network mgmt_priority {0-7}`
Control VLAN ID¹	The Control VLAN on the pack. It applies to VLNC6x circuit packs only. By default the value of Control VLAN ID is the same as that of Management VLAN ID. Valid values: an integer in the range of 1 to 4094 or None.	`network cntl_vlan <vlanid>`
¹This command configures the control VLAN ID on the pack. The pack uses this VLAN to send control traffic (ARP, ping, and telnet) to IP addresses in different subnet from its network port. For example if the IP address of the network port is 100.100.10.10 (mask 255.255.0.0) then ARP traffic to resolve 20.20.10.10 (or ping for 200.200.10.10) will be sent over the control VLAN ID on the pack. The pack generates the control traffic above during ARP resolution of PSN Tunnel, sending ping requests towards other endpoint of PSN Tunnel, telnet to other endpoint of PSN Tunnel. The pack will continue to send control traffic for the IP address on the same subnet as its network port, over management VLAN. In the above example, ARP traffic to resolve 100.100.10.20 (or ping towards 100.100.10.20) will be sent over management VLAN on the pack.
