| Table 85 Bandwidth Management Rule Configuration (continued) | ||
| LABEL | DESCRIPTION |
|
| BW Budget | Specify the maximum bandwidth allowed for the rule in kbps. The |
|
|
| recommendation is a setting between 20 kbps and 20000 kbps for an individual |
|
|
| rule. |
|
|
|
|
|
| Priority | Select a priority from the drop down list box. Choose High, Mid or Low. |
|
|
|
|
|
| Use All Managed | Select this option to allow a rule to borrow unused bandwidth on the interface. |
|
| Bandwidth | Bandwidth borrowing is governed by the priority of the rules. That is, a rule with |
|
|
| the highest priority is the first to borrow bandwidth. Do not select this if you want |
|
|
| to leave bandwidth available for other traffic types or if you want to restrict the |
|
|
| amount of bandwidth that can be used for the traffic that matches this rule. |
|
|
|
|
|
| Filter Configuration |
|
|
|
|
|
|
| Service | This field simplifies bandwidth class configuration by allowing you to select a |
|
|
| predefined application. When you select a predefined application, you do not |
|
|
| configure the rest of the bandwidth filter fields (other than enabling or disabling |
|
|
| the filter). |
|
|
| SIP (Session Initiation Protocol) is a signaling protocol used in Internet |
|
|
| telephony, instant messaging and other VoIP (Voice over IP) applications. |
|
|
| Select SIP from the |
|
|
| that uses SIP. |
|
|
| File Transfer Protocol (FTP) is an Internet file transfer service that operates on |
|
|
| the Internet and over TCP/IP networks. A system running the FTP server |
|
|
| accepts commands from a system running an FTP client. The service allows |
|
|
| users to send commands to the server for uploading and downloading files. |
|
|
| Select FTP from the |
|
|
| traffic. |
|
|
| H.323 is a standard teleconferencing protocol suite that provides audio, data |
|
|
| and video conferencing. It allows for |
|
|
| communication between client computers over a |
|
|
| does not provide a guaranteed quality of service. Select H.323 from the drop- |
|
|
| down list box to configure this bandwidth filter for traffic that uses H.323. |
|
|
| Select User defined from the |
|
|
| predefined application for the bandwidth class. When you select User defined, |
|
|
| you need to configure at least one of the following fields (other than the Subnet |
|
|
| Mask fields which you only enter if you also enter a corresponding destination or |
|
|
| source IP address). |
|
|
|
|
|
| Destination | Enter the destination IP address in dotted decimal notation. |
|
| Address |
|
|
|
|
|
|
| Destination Subnet | Enter the destination subnet mask. This field is N/A if you do not specify a |
|
| Netmask | Destination Address. Refer to the appendices for more information on IP |
|
|
| subnetting. |
|
|
|
|
|
| Destination Port | Enter the port number of the destination. See Table 86 on page 214 for some |
|
|
| common services and port numbers. A blank destination IP address means any |
|
|
| destination IP address. |
|
|
|
|
|
| Source Address | Enter the source IP address in dotted decimal notation. A blank source IP |
|
|
| address means any source IP address. |
|
|
|
|
|
| Source Subnet | Enter the destination subnet mask. This field is N/A if you do not specify a |
|
| Netmask | Source Address. Refer to the appendices for more information on IP |
|
|
| subnetting. A blank source port means any source port number. |
|
|
|
|
|
| Source Port | Enter the port number of the source. See Table 86 on page 214 for some |
|
|
| common services and port numbers. |
|
