This functionality allows you to block the traffic of certain protocols. To use this functionality, you must enable the URL filtering functionality, as well as enable and configure dpilist (see the “URL Filtering configuration” section). You can use any of the 16 lists.
In the URL filtering list settings, blocked protocols are specified in the protocols parameter. You can specify one or several protocols (separated by a space), and also add/delete individual protocols using the “+=” and “-=” operands if necessary.
Protocol blocking is limited to dpilist, in which they are specified, and by the ip and ipv6 parameters of that dpilist.
For any traffic operations, you must also configure pools and ACLs (see the section “Pools and ACL”).
The list of protocols is invoked by the show protocols all command in the system dpi branch.
To quickly search for protocols by name, enter the first letters of the name after the show protocols and press the [Tab] key. If there are several options, a list of matches will be displayed. If there is one option, then after pressing the [Tab] key, the protocol abbreviation will be displayed. For example:ECOHOST:7:system.dpi# show protocols ss [TAB]
# There are several choices:
ssdp
ssh
ssl
sscopmce
ss
To display a description of a specific protocol, enter its abbreviation after the show protocols command and press the [Enter] key. For example:
ECOHOST:7:system.dpi# show protocols ssh
name ssh
full name Secure Shell
description Secure Shell (SSH), sometimes known as Secure Socket Shell, is a UNIX-based command interface and a protocol for obtaining secure access to a remote computer.
