ToS Bit Manipulation Configuration

This section provides instructions for how to configure TOS bit manipulation on your Oracle® Enterprise Session Border Controller.

To configure TOS bit manipulation:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```

Type media-manager and press Enter.

ORACLE(configure)# media-manager
ORACLE(media-manager)#

Type media-policy and press Enter.
```
ORACLE(media-manager)# media-policy
```
If you are adding support for this feature to a pre-existing configuration, then you must select (using the ACLI select command) the configuration you want to edit.
name—Create a reference name for this policy and press Enter.
Type tos-settings and press Enter.
```
ORACLE(media-policy)# tos-settings
```
Note:
The media-policy > tos-settings parameter is not RTC supported and a reboot is required for these updates to take affect.
media-type—Enter the media type that you want to use for this group of TOS settings. You can enter any of the IANA-defined media types for this value: audio, example, image, message, model, multipart, text, and video. This value is not case-sensitive and can be up to 255 characters in length; it has no default.
```
ORACLE(tos-settings)# media-type message
```
media-sub-type—Enter the media sub-type you want to use for the media type. This value can be any of the sub-types that IANA defines for a specific media type. This value is not case-sensitive and can be up to 255 characters in length; it has no default.
```
ORACLE(tos-settings)# media-sub-type sip
```
media-attributes—Enter the media attribute that will match in the SDP. This parameter is a list, so you can enter more than one value. The values are case-sensitive and can be up to 255 characters in length. This parameter has no default.
If you enter more than one media attribute value in the list, then you must enclose your entry in quotation marks ().
```
ORACLE(tos-settings)# media-attributes sendonly sendrecv
```
tos-value—Enter the TOS value you want applied for matching traffic. This value is a decimal or hexidecimal value. The valid range is:
- 0x00 to 0xFF.
```
ORACLE(tos-settings)# tos-value 0xF0
```
Save and activate your configuration.
