  • Smart Licensing and Specific License Reservation

  • Quality of Service/Cisco Application Visibility and Control (AVC)

  • VLAN/VTP


Note

The VLANs feature is supported only on routers with switch port module or routers with built-in switch port.


Entering the Configuration Commands Manually

To enter the Cisco IOS commands manually, complete the following steps:

Before you begin

If you do not want to use the factory default configuration because the router already has a configuration, or for any other reason, you can use the procedure in this section to add each required command to the configuration.

Procedure


Step 1

Log on to the router through the Console port or through an Ethernet port.

Step 2

If you use the Console port, and no running configuration is present in the router, the Setup command Facility starts automatically, and displays the following text:

--- System Configuration Dialog ---
 
Continue with configuration dialog? [yes/no]:

Enter no so that you can enter Cisco IOS CLI commands directly.

If the Setup Command Facility does not start automatically, a running configuration is present, and you should go to the next step.

Step 3

When the router displays the user EXEC mode prompt, enter the enable command, and the enable password, if one is configured, as shown in the following example:

Router> enable
password password
Step 4

Enter config mode by entering the configure terminal command, as shown in the following example.

Router> config terminal
Router(config)#
Step 5

Using the command syntax shown, create a user account with privilege level 15.

Step 6

If no router interface is configured with an IP address, configure one so that you can access the router over the network. The following example shows the interface Fast Ethernet 0 configured.

Router(config)# int FastEthernet0
Router(config-if)# ip address 10.10.10.1 255.255.255.248
Router(config-if)# no shutdown
Router(config-if)# exit
Step 7

Configure the router as an http server for nonsecure communication, or as an https server for secure communication. To configure the router as an http server, enter the ip http server command shown in the example:

Router(config)# ip http secure-server
Step 8

Configure the router for local authentication, by entering the ip http authentication local command, as shown in the example:

Router(config)# ip http authentication local
Step 9

Configure the vty lines for privilege level 15. For nonsecure access, enter the transport input telnet command. For secure access, enter the transport input telnet ssh command. An example of these commands follows:

Router(config)# line vty 0 4
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport output telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# transport output telnet ssh
Router(config-line)# exit
Router(config)# line vty 5 15
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport output telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# transport output telnet ssh
Router(config-line)# end
 

Open and Resolved Bugs for Cisco IOS XE Gibraltar 16.10.1b

This section provides information about the caveats in Cisco 1100 Series Integrated Services Routers and describe unexpected behavior. Severity 1 caveats are the most serious caveats. Severity 2 caveats are less serious. Severity 3 caveats are moderate caveats. This section includes severity 1, severity 2, and selected severity 3 caveats.

The open and resolved bugs for this release are accessible through the Cisco Bug Search Tool. This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in this product and other Cisco hardware and software products. Within the Cisco Bug Search Tool, each bug is given a unique identifier (ID) with a pattern of CSCxxNNNNN, where x is any letter (a-z) and N is any number (0-9). The bug IDs are frequently referenced in Cisco documentation, such as Security Advisories, Field Notices and other Cisco support documents. Technical Assistance Center (TAC) engineers or other Cisco staff can also provide you with the ID for a specific bug. The Cisco Bug Search Tool enables you to filter the bugs so that you only see those in which you are interested.

In addition to being able to search for a specific bug ID, or for all bugs in a product and release, you can filter the open and/or resolved bugs by one or more of the following criteria:

  • Last modified date

  • Status, such as fixed (resolved) or open

  • Severity

  • Support cases

You can save searches that you perform frequently. You can also bookmark the URL for a search and email the URL for those search results.


Note

If the defect that you have requested cannot be displayed, this may be due to one or more of the following reasons: the defect number does not exist, the defect does not have a customer-visible description yet, or the defect has been marked Cisco Confidential.
