Create Port Profile

While you cannot modify predefined port profiles, Junos Space does allow you to create new port profiles that are similar to the predefined profiles but with a few parameters that you can customize. These profiles will retain the values of the original port profile until you change it. To create a customized port profile, you need to configure one or more of the following settings:

General Settings

Configuring general settings for a customized port profiles includes setting parameters such as a name and description for the profile. Junos Space automatically generates a profile name for the new customized profile. For example, DesktopPort_1.

CoS Settings

A scheduler configuration block specifies the buffer size, bandwidth, and priority for a queue. By defining schedulers, you can configure the properties of output queues that determine the transmission service level for each queue. These properties include the amount of interface bandwidth assigned to the queue, the size of the memory buffer allocated for storing packets, and the priority of the queue. After defining schedulers you associate them with forwarding classes by means of scheduler maps. By default, the schedulers values are already set.

Forwarding classes allow you to group packets for transmission. You then associate each scheduler map with an interface, and configure the hardware queues and packet schedulers that operate according to this mapping.

When applying or provisioning a port role to an interface, you must map the forwarding classes and schedulers using the scheduler map.

The schedulers and their settings are:

• Voice- The transmission rate is set to 10 percent and buffer size to 5 percent.
• Expedited-forwarding - The transmission rate is set to 30 percent, the buffer size to 30 percent, and priority is set to low.
• Assured-forwarding - The transmission rate is set to 25 percent, the buffer size to 25 percent, and priority is set to low.
• Best-effort - The transmission-rate is set to 35 percent, the buffer size to 40 percent, and priority is set to low.

These are the settings for the Juniper predefined port profiles. While customizing, you can change the transmission rate and buffer size to optimize your communication with the network. You must ensure that the cumulative bandwidth and buffer percentages is always be 100 percent or less. For example, if the total bandwidth percentage already adds up to 100, you must reduce the bandwidth of one of the categories to increase the bandwidth of another.

Ethernet Switching Options

You can use the Ethernet Switching Options page to set the broadcast limit for network traffic. The broadcast limit is the theoretical maximum of network bandwidth in percent that can be used for broadcast and multicast traffic. Any broadcast or multicast traffic exceeding that limit will be dropped. A zero value (0) indicates that the feature is disabled.

To create a customized port profile, follow these steps:

1. From the task ribbon, select EZ Campus Design > Port Profile > Create Port Profile. This opens the Create Port Profile wizard.
2. Enter a name for the profile in the Profile Name field.
3. Select the port profile that you want to customize from the Profile type drop down list. The Profile Details field appears showing information about the customized profile such as the roles or actions that the port will be able to perform after the port profile has been applied to it. This content in this field varies depending on the port profile that you have selected.
4. Enter a description for the customized profile in the Profile Description field.
5. The settings that are available for customization vary based on the port profile. The description of the six port profiles and the settings that are available for customization is provided in Table 1.

   Table 1: Port Profile Descriptions and Customization Options

   Port Profile	Description and Customization Options
   Desktop Port	A desktop port enables you to connect a desktop to a switch port. By applying this profile to the port, you are configuring settings such as the VLAN, port security, and RSTP settings. For more information about the CLI commands used in a desktop port profile, see Desktop Port Profile CLI . The customizing options that are available for this profile are: General Settings. Ethernet Switching Options. For more information on customizing a desktop port profile, see Creating a Customized Desktop Port Profile.
   Desktop and phone port	A desktop and phone port enables you to connect a desktop and phone port to a switch port. By applying this profile to the port, you are configuring settings such as port security, RSTP, and CoS settings. For more information about the CLI commands used in a desktop and phone port profile, see Desktop and Phone Port Profile CLI . The customizing options that are available for this profile are: General Settings. CoS Settings. Ethernet Switching Options. For more information on customizing a desktop and phone port profile, see Creating a Customized Desktop and Phone Port Profile
   Switched Uplink Port	A switched uplink port enables you to connect a switch port on the access layer to a switch port on the distribution layer. By applying this profile to the port, you are configuring settings such as VLAN, port security, and CoS settings. For more information about the CLI commands used in a switched uplink port profile, see Switched Uplink Port Profile CLI . The customizing options that are available for this profile are: General Settings. CoS Settings. For more information on customizing a switched uplink port profile, see Creating a Customized Switched Uplink Port Profile.
   Switched Downlink Port	A switched downlink port enables you to connect a switch port on the distribution layer to a switch layer on the access layer. By applying this profile to the port, you are configuring settings such as VLAN, port security, and CoS settings. For more information about the CLI commands used in a switched downlink port profile, see Switched Downlink Port Profile CLI . The customizing options that are available for this profile are: General Settings. CoS Settings. For more information on customizing a switched downlink port profile, see Creating a Customized Switched Downlink Port Profile.
   Server Port	A server port is a trunk port that enables users from multiple VLANs to connect to a machine with virtual servers. By applying this profile to the port, you are configuring settings such as VLAN, RSTP, and CoS settings. For more information about the CLI commands used in a server port profile, see Server Port Profile CLI . The customizing options that are available for this profile are: General Settings. CoS Settings. Ethernet Switching Options. For more information on customizing a server port profile, see Creating a Customized Server Port Profile.
   Wireless Access Point Port	A wireless access point port enables you to connect a wireless access point, which is a device that allows wireless communication devices to connect to a wireless network using Wi-Fi, Bluetooth or related standards, to a switch port. By applying this profile to the port, you are configuring settings such as VLAN, RSTP, and CoS settings. For more information about the CLI commands used in a wireless access point port profile, see Wireless Access Point Port Profile CLI . Note: Junos Space does not allow you to customize a wireless access point port profile.

6. Click Back to go to the previous step of the Customize Port Profile wizard. Click Create to save your changes and create a new customized profile. The customized port profile appears on the Port Profile page. Click Cancel to go back to the Port Profile page without creating a new port profile.
