When you configure the interfaces associated with a provisioned switch (for example, as part of a VLAN), the switch stack accepts the configuration, and the information appears in the running configuration. The new switch is added to the switch stack. After a new stack master is elected and the previous stack master becomes available, the previous stack master does not resume its role as stack master. The configuration files include the system-level settings for the switch stack and the interface-level settings for each stack member. The replacement switch (referred to as the provisioned switch) must have the same stack member number as the failed switch. Auto-copy starts, finds suitable software to copy from a stack member to the switch in VM mode, upgrades the switch in VM mode, and then reloads it: This example shows that the switch stack detected a new switch that is running a different minor version number than the switch stack.

If the entire switch stack reloads, the switch stack uses the MAC address of the stack master.
Reenable the link between the switches.
You manually create the provisioned configuration through the switch stack-member-number provision type global configuration command. Auto-upgrade includes an auto-copy process and an auto-extract process. Displays information about a specific member. You can access all or specific members by using the remote command {all | stack-member-number} privileged EXEC command. To avoid a conflict by having two devices with the same IP address in your network, change the IP addresses of any switches that you remove from the switch stack. If one or both of these LEDs are not green on any of the switches, the stack is not operating at full bandwidth.
You manage the switch stack and the stack member interfaces through the stack master. If the switch stack does not contain a provisioned configuration for a new switch, the switch joins the stack with the default interface configuration. When a new switch attempts to join a switch stack, each stack member performs compatibility checks with itself and the new switch. We recommend assigning the highest priority value to the switch that you prefer to be the stack master. The interface-specific configuration of each stack member is associated with the stack member number.
The stack master assigns a new stack member number to the provisioned switch. The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores leading spaces. Depending on the switch model, the last two right ports are 10-Gigabit Ethernet ports or small form-factor pluggable (SFP) module ports (10/100/1000 ports). Step 5 Enter a virtual terminal (Telnet) password, and press Return. All rights reserved. For more information about the info file, see the Catalyst 2960-X Switch Managing Cisco IOS Image Files Configuration Guide. Assuming that one stack member has a higher priority value than the other stack member: The stack member with the higher priority value retains its stack member number. To debug a specific stack member, you can access it from the stack master by using the session stack-member-number privileged EXEC command. To change the priority value for a stack member, use the switch stack-member-number priority new priority-value global configuration command. The stack member number range is 1 to 8. When you disable a stack port and the stack is in the full-ring state, you can disable only one stack port. The following table shows the default switch stack configuration settings: 2. stack-mac persistent timer [0 | time-value]. 2. no switch stack-member-number provision. Only the show and debug commands are available in a CLI session to a specific stack member. To receive security and technical information about your products, you can subscribe to various services, such as the Product Alert Tool (accessed from Field Notices), the Cisco Technical Services Newsletter, and Really Simple Syndication (RSS) Feeds. The port LEDs on switches in version-mismatch mode will also remain off. The software uses the automatic upgrade (auto-upgrade) and the automatic advise (auto-advise) features. The interface associated with the provisioned switch does not appear in the display of the specific feature; for example, it does not appear in the show vlan user EXEC command output. For example, Switch-2# is the prompt in privileged EXEC mode for stack member 2, and the system prompt for the stack master is Switch. 12.2(44)SE, Configuration Note for Catalyst 2960 Switch Power over Ethernet Ports, Rel. To completely remove the configuration, use the no switch stack-member-number provision global configuration command. The startup configuration file ensures that the switch stack can reload and can use the saved information whether or not the provisioned switch is part of the switch stack. When a single link in a full ring stack becomes inoperable, there is a disruption in the forwarding of packets, and the stack moves to a half ring. The last two right port LEDs on all switches in the stack should be green. 12.2(44)SE, Catalyst 2960 Switch Software Configuration Guide, Rel. The stack member number is not found in the provisioned configuration. For switch stack hardware considerations, see the Catalyst 2960-X Switch Hardware Installation Guide. Displays information about HULC feature compatibility. If you add a provisioned switch that is a different type than specified in the provisioned configuration to a powered-down switch stack and then apply power, the switch stack rejects the (now incorrect) switch stack-member-number provision type global configuration command in the startup configuration file. The configuration that you create on the switch stack is called the provisioned configuration. You can connect to the stack master by using one of these methods: Be careful when using multiple CLI sessions to the stack master. Book Title. You can configure the stack member number, the switch type, and the interfaces associated with a switch that is not currently part of the stack. You cannot manage stack members on an individual switch basis. show controller ethernet-controller fastethernet0. You need to press Enter to display the setup program prompt. Follow these steps to connect the PC or terminal to the switch: Step 1 Using the supplied RJ-45-to-DB-9 adapter cable, insert the RJ-45 connector into the console port on the rear of a switch, as shown in Figure C-1.
