If ttyb is already in use, use ttya instead and enter the following string at the prompt:
tip /dev/ttya -9600
Setting the switch IP address
You can configure the switch with a static IP address, or you can use a Dynamic Host Configuration
Protocol (DHCP) server to set the IP address of the switch. DHCP is enabled by default. The switch
supports both IPv4 and IPv6.
Using DHCP to set the IP address
When using DHCP, the switch obtains its IP address, subnet mask, and default gateway address from
the DHCP server. The DHCP client can only connect to a DHCP server that is on the same subnet as
the switch. If your DHCP server is not on the same subnet as the switch, use a static IP address.
Setting a static IP address
1. Log in to the switch using the default password, which is password.
2. Use the ipaddrset command to set the Ethernet IP address.
If you are going to use an IPv4 IP address, enter the IP address in dotted decimal notation as
prompted.
Ethernet IP Address: [192.168.74.102]
If you are going to use an IPv6 address, enter the network information in colon-separated notation
as prompted.
switch:admin> ipaddrset -ipv6 --add 1080::8:800:200C:417A/64
IP address is being changed...Done.
3. Complete the rest of the network information as prompted. (IPv4 format shown):
Ethernet Subnetmask: [255.255.255.0]
Ethernet IP Address: [192.168.74.102]
Gateway IP Address: [192.168.74.1]
4. Enter off to disable DHCP when prompted.
DHCP [OFF]: off
Changing the switch name and chassis name
Changing the switch and chassis names are important for accurate tracking of errors in the RASlog.
The messages that appear in the log will be labeled with the switch or chassis name, which makes
tracking the errors much easier. Choose an easily understandable and meaningful name for the switch
and chassis names.
Perform the following steps to change the chassis name and then the switch name.
1. Log in to the switch through Telnet using the admin account.
2. Change the chassis name by using the chassisName command.
switch:admin> chassisname my7840chassis
3. Change the switch name by using the switchName command.
switch:admin> switchname my7840switch
