This appendix describes how to recover a LocalDirector image on a LocalDirector 417 platform from the network using the boot loader program. Topics include:
LocalDirector 417 has a resident boot loader function that lets you reload the LocalDirector image from a TFTP server on the network should the LocalDirector image become corrupted.
When you boot LocalDirector, the boot loader program runs first and is responsible for loading the LocalDirector image. If the boot loader detects that the LocalDirector image is corrupt, then the boot loader program is automatically invoked. At this point, you can run boot loader commands to reload the LocalDirector image from the network.
 |
Note To use the boot loader program to recover the LocalDirector image, you must connect the LocalDirector 417 port labeled Ethernet 0 to the same network segment or VLAN that has the TFTP server. The boot loader is only capable of using interface 0 on the LocalDirector 417 system. All other network interfaces are inoperable while the boot loader is in use. |
Refer to Chapter 3, "Installing LocalDirector 417," in the Cisco LocalDirector 417 Hardware Installation Guide for additional hardware installation information.
To use the boot loader program to recover a corrupted LocalDirector software image, perform the following steps:
Step 2 Boot LocalDirector 417. When "Boot Loader Version 1.0.0.x ......" appears, press Esc Esc Ctrl-B while the ellipses (.....) are progressing to invoke the boot loader.
The following example shows the display that appears after you boot LocalDirector and invoke the boot loader program.

To add an entry to the LocalDirector Address Resolution Protocol (ARP) table, use the arp command. Use the no arp command to remove an ARP entry.
arp ip mac_address interface_number [alias]
Syntax Description
ip IP address for the ARP table entry. mac_address Hardware MAC address for the ARP table entry. interface_number Interface number. alias (Optional) Alias entries do not time out.
Defaults
No default behavior or values.
Usage Guidelines
The arp command adds an entry to the LocalDirector ARP table. ARP is a low-level protocol that maps the physical address of a node to its IP address.
Examples
boot> show arp
boot> arp 206.50.10.100 00e0.b600.810f 0
boot> show arp
ifc 0 206.50.10.100 00e0.b600.810f

To configure network interfaces for LocalDirector, use the interface command.
interface ethernet interface_number{10baset | 100basetx | 100full | 1000basesx | 1000full

Defaults
No default behavior or values.
Usage Guidelines
The ip address command assigns an IP address to LocalDirector. Use the show ip address command to view the address. The ip route command is used to map a remote destination network to the LocalDirector network through a default gateway (router).
Examples
boot> show ip route
ip address 172.16.10.110 255.255.255.0
boot> ip route 10.0.0.0 255.0.0.0 206.50.10.2

To specify the maximum transmission unit (MTU) value for the specified network interface, use the mtu command.
mtu unit bytes [64-65535]
Syntax Description
unit Unit number. bytes MTU for the interface. Specify a number from 64 to 65535.
Defaults
For Ethernet interfaces, the default MTU should be 1500 bytes in a block.
Usage Guidelines
The value for the mtu command depends on the type of network interface specified in the interface command. The minimum value for bytes is 64 and the maximum is 65535 bytes.
Examples
boot> show mtu
mtu 0 1500
mtu 1 1500
mtu 2 1500
mtu 3 1500
boot> mtu 1 1000

To send a ping request message, use the ping command.
ping ip_address
Syntax Description
ip_address IP address of a host on the network.
Defaults
No default behavior or values.
Usage Guidelines
The ping command determines whether LocalDirector has connectivity or whether a host is available on the network. The command output shows whether the response was received; that is, that the host exists on the network. If the host is not responding, the ping command results in this message:
no response received
Use the show interface command to ensure that LocalDirector is connected to the network and has connectivity.
Examples
In the following example, three attempts reached the specified address:
boot> ping 172.16.5.98
172.16.5.98 response received -- 0ms
172.16.5.98 response received -- 0ms
