CSS Login and File System Access

CSS Login and File System Access

Two switches in a CSS form a virtual switch on the network, and the interface numbering rules, system login methods, and file system access methods used in the CSS are different from those used on standalone switches.

Interface Numbering Rules

On a standalone switch with CSS disabled, interfaces are numbered in the slot ID/subcard ID/port sequence number format. In a CSS, member switches are identified by their CSS IDs and their interfaces are numbered in the CSS ID/slot ID/subcard ID/port sequence number format.

For example, an interface on a standalone switch with CSS disabled is numbered GigabitEthernet1/0/1. After the switch joins a CSS and is assigned CSS ID 2, the interface number changes to GigabitEthernet2/1/0/1.

The management interface in a CSS is numbered Ethernet0/0/0/0.

NOTE:

After you enable CSS on a standalone switch and restart the switch, the switch becomes a single-chassis CSS and its interfaces are numbered in the CSS ID/slot ID/subcard ID/port sequence number format.

After CSS is disabled on a switch, the interface numbering format on the switch must be manually changed from CSS ID/slot ID/subcard ID/port sequence number to slot ID/subcard ID/port sequence number. The procedure is as follows:
  1. After CSS is enabled on the switch, the switch automatically backs up the configuration file used in standalone state by adding the file name extension .bak to the configuration file name.
  2. Before CSS is disabled on the switch, specify this backup configuration file for next startup.
  3. Disable CSS and then restart the switch.

CSS Login

You can log in to a CSS using the following methods:

  • Local login

    Log in through the console interface on any MPU of the CSS.

  • Remote login

    Log in through the management interface or another Layer 3 interface of any MPU in the CSS. You can remotely log in to the CSS using Telnet, STelnet, web, or SNMP if your operation terminal has a reachable route to the CSS.

After logging in to a CSS, you have actually logged in to the master switch, no matter which member switch you logged in through. After you perform configurations in the CSS, the master switch issues the configurations to the standby switch. In this way, resources of member switches are managed uniformly.

File System Access

File system access refers to operations performed on the storage device, including file/directory creation, deletion, and modification, and file display.

The location of a file is identified by one of the following:
  • drive indicates the storage device.

  • path indicates a directory and its sub-directories.

  • filename indicates the file name.

For details, see Overview of the File System in "File Management" in the S7700 and S9700 V200R013C00 Configuration Guide - Basic Configuration.
The value of drive varies in a standalone switch and a CSS.
  • In a standalone switch:
    • To access the root directory of the CF card or flash memory on the system master MPU, set drive to cfcard: or flash:.
    • To access the root directory of the CF card or flash memory on the standby MPU, set drive to slave#cfcard: or slave#flash:.
  • In a CSS:
    • To access the root directory of the CF card or flash memory on the system master MPU, set drive to cfcard: or flash:.
    • To access the root directory of the CF card or flash memory on the system standby MPU or candidate system standby MPU, set drive to chassis ID/slot ID#cfcard: or chassis ID/slot ID#flash:. (The chassis ID is the CSS ID.)

      For example, 1/8#cfcard: indicates the root directory of the CF card in slot 8 of chassis 1.
