Selection of Source/Destination Ports should be done only if you are aware of the port usage of
the desired protocol or application. There are well known ports for various protocols, but often
only the ‘command’ messaging is transacted on these ports and the ‘data’ is transferred through
a negotiated port.
Use this table as a reference for some well-known port numbers:
Port Description Port Description
1 TCP Port Service Multiplexer (TCPMUX) 118 SQL Services
7 ECHO 119 Newsgroup (NNTP)
20 FTP - Data 137 NetBIOS Name Service
21 FTP - Control 139 NetBIOS Datagram Service
22 SSH Remote Login Protocol 150 NetBIOS Session Service
23 Telnet 156 SQL Server
25 Simple Mail Transfer Protocol (SMTP) 161 SNMP
42 Host Name Server (Nameserv) 179 Border Gateway Protocol (BGP)
53 Domain Name System (DNS) 190 Gateway Access Control Protocol (GACP)
69 Trivial File Transfer Protocol (TFTP) 197 Directory Location Service (DLS)
70 Gopher Services 396 Novell Netware over IP
80 HTTP 443 HTTPS
108 SNA Gateway Access Server 444 Simple Network Paging Protocol (SNPP)
109 POP2 546 DHCP Client
110 POP3 547 DHCP Server
115 Simple File Transfer Protocol (SFTP) 1080 Socks
Once the QoS Rules are defined, each type of traffic flow should be isolated and
sent to verify that it is being sent in the intended QoS Rule.
WRED – When WRED is enabled for a specific queue, QoS randomly drops packets after
reaching 50% of the QoS queue.
L.1.1.1 Max/Pri QoS Mode Example
Dop these steps:
1. Select Max/Pri QoS mode.
2. Set Modem Tx bandwidth to 2048 Kbps (E1 rate).
3. Configure the Max/Pri QoS rules as follows:
