Configuring Management Interfaces on Cisco IOS XR Software

Transcription

1 Configuring Management Interfaces on Cisco IOS XR Software This module describes configuration procedures for management interfaces on the route processors (RPs). Although the management interfaces on the system are present by default, the user must configure these interfaces to use them for accessing the router via protocols and applications such as Simple Network Management Protocol (SNMP), Common Object Request Broker Architecture (CORBA), HTTP, extensible markup language (XML), TFTP, Telnet, and command-line interface (CLI). Note The CRS-1 Series router RP is equipped with a Gigabit Ethernet interface. Feature History for Configuring Management Interfaces on Cisco IOS XR Software Release Release 2.0 Release 3.0 Release 3.2 Modification This feature was introduced. No modifications. This feature was first supported on the Cisco XR Series Router.

2 Prerequisites for Configuring Management Ethernet Interfaces Configuring Management Interfaces on Cisco IOS XR Software Prerequisites for Configuring Management Ethernet Interfaces Before configuring an Management Ethernet interface, be sure the following tasks and conditions are met: To use the cdp command, you must be in a user group associated with a task group that includes the proper task IDs for Cisco Discovery Protocol (CDP) commands. To use the speed and full-duplex commands, you must be in a user group associated with a task group that includes the proper task IDs for interface commands. Task IDs for commands are listed in the Cisco IOS XR Task ID Reference Guide. You know the interface IP address. You know the interface subnet mask. You know how to apply the generalized interface name specification rack/slot/module/port. For further information on interface naming conventions, refer to the Cisco IOS XR Getting Started Guide. Note Note that, for transparent switchover, both active and standby interfaces are expected to be physically connected to the same LAN or switch. Information About Configuring Management Interfaces To configure management interfaces, you need to understand the following concept: Default Interface Settings, page HC-48 Default Interface Settings The default interface settings shown in Table 3 can be changed by configuration. Default settings are not displayed in the output from the show running-config command. Table 3 Management Ethernet Interface Default Settings Parameter Configuration File Entry Default Value Cisco Discovery Protocol (CDP) cdp cdp disable Speed in Mbps speed [ ] no speed [ ] Duplex mode (exclusive command) full-duplex no full-duplex half-duplex no half-duplex MAC address mac-address address no mac-address address no speed (autonegotiation) no full-duplex no half-duplex (autonegotiation) no mac-address (read the BIA) HC-48

3 Configuring Management Interfaces on Cisco IOS XR Software How to Configure Management Ethernet Interfaces Note Forwarding between PLIM ports and Management Ethernet ports is disabled by default. To enable forwarding between PLIM ports and Management Ethernet ports, use the rp mgmtethernet forwarding command. How to Configure Management Ethernet Interfaces This section contains the following procedure: Configuring a Management Ethernet Interface, page HC-49 Configuring a Management Ethernet Interface SUMMARY STEPS DETAILED STEPS Perform this task to configure the Management Ethernet interfaces for the RPs. 1. configure 2. interface type instance 3. ipv4 address ip-address 4. cdp 5. full-duplex 6. speed { } 7. no shutdown 8. end or commit 9. show interfaces type instance 10. show running-config Step 1 Command or Action configure Purpose Enters global configuration mode. Step 2 RP/0/RP0/CPU0:router# configure interface type instance RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP0/CPU0/0 Enters interface configuration mode and specifies the management interface name and instance.

4 How to Configure Management Ethernet Interfaces Configuring Management Interfaces on Cisco IOS XR Software Step 3 Step 4 Step 5 Command or Action ipv4 address ip-address RP/0/RP0/CPU0:router(config-if)# ipv4 address /24 cdp RP/0/RP0/CPU0:router(config-if)# cdp full-duplex Purpose Assigns an IP address and subnet mask to the management interface. (Optional) Enables CDP on the interface. Note To disable CDP, use the no form of this command, as follows: no cdp. (Optional) Configures the interface duplex mode. RP/0/RP0/CPU0:router(config-if)# full-duplex Step 6 speed { } (Optional) Configures the interface speed parameter. RP/0/RP0/CPU0:router(config-if)# speed 100 Step 7 no shutdown Removes the shutdown configuration. Step 8 Step 9 end or commit RP/0/0/CPU0:router(config-if)# end or RP/0/0/CPU0:router(config-if)# commit show interfaces type instance Saves configuration changes. When you issue the end command, the system prompts you to commit changes: Uncommitted changes found, commit them before exiting(yes/no/cancel)? [cancel]: Entering yes saves configuration changes to the running configuration file, exits the configuration session, and returns the router to EXEC mode. Entering no exits the configuration session and returns the router to EXEC mode without committing the configuration changes. Entering cancel leaves the router in the current configuration session without exiting or committing the configuration changes. Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session. Displays the management interface configuration. Step 10 RP/0/RP0/CPU0:router# show interfaces MgmtEth 0/RP0/CPU0/0 show running-config Displays the running configuration. RP/0/RP0/CPU0:router# show running-config HC-50
