Introduction (download full document here cisco_configuration_guide.pdf )
The following document deals purely with the configuration of 3560 switches used in ISIS8000 systems under nCC V5
control. It covers both TS data and TS output switches.
Cisco switches are becoming more and more common in TANDBERG systems as they are used to interface various products to customer IP networks. The switches can be used in many roles with in the system. The following document is designed to assist setting up Cisco equipment for use with nCompass Control and iSIS8000 systems.
This document gives an overview of all the functions associated with Cisco switches when used with nCompass Control. The document is only to be used as a guide to assist engineers in setting up and configuring switches.
The following instructions for setting up switches in the following modes are covered:-
Cisco switches can be used in nCompass Control to carry broadcast traffic over IP. nCompass can currently control specific Cisco switch models for device redundancy. The operation of the switch is controlled by SNMP.
nCompass can currently support the following switches for device control:-
There are currently two software versions available on the Cisco 3550/60. There is no difference in hardware between an SMI and EMI switch. The two software versions are Enhanced Multilayer Image (EMI) and Standard Multilayer Image (SMI). EMI provides more features such as enhanced security, Quality of Service (QoS), OSPF Routing and Protocol Independent Multicast (PIM). IP streamer and encoder systems can use an SMI switch unless specified otherwise.
Cisco 2950 switches are used for Management network redundancy only.
The following is intended as a guide to configure Cisco catalyst switches to work with nCompass. If a GigE switch (i.e. Cisco 3560G) is being used the replace all instances of fa0/? With gi0/?
The following gives a brief set of instructions for setting up a Cisco 3560 as a TS Data switch.
Clearing the Current Configuration
This is recommended if the switch has been previously used.
Current configuration : 1312 bytes ! version 12.2 no service pad service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Switch (DEFAULT HOSTNAME) ! ! no aaa new-model ip subnet-zero ! ! no file verify auto spanning-tree mode pvst spanning-tree extend system-id ! vlan internal allocation policy ascending ! interface GigabitEthernet0/1 (NO VLAN’S ASSIGNED) ! interface GigabitEthernet0/2 ! interface GigabitEthernet0/3 ! interface GigabitEthernet0/4 ! interface GigabitEthernet0/5 ! interface GigabitEthernet0/6 ! interface GigabitEthernet0/7 ! interface GigabitEthernet0/8 ! interface GigabitEthernet0/9 ! interface GigabitEthernet0/10 ! interface GigabitEthernet0/11 ! interface GigabitEthernet0/12 ! interface GigabitEthernet0/13 ! interface GigabitEthernet0/14 ! interface GigabitEthernet0/15 ! interface GigabitEthernet0/16 ! interface GigabitEthernet0/17 ! interface GigabitEthernet0/18 ! interface GigabitEthernet0/19 ! interface GigabitEthernet0/20 ! interface GigabitEthernet0/21 ! interface GigabitEthernet0/22 ! interface GigabitEthernet0/23 ! interface GigabitEthernet0/24 ! interface GigabitEthernet0/25 ! interface GigabitEthernet0/26 ! interface GigabitEthernet0/27 ! interface GigabitEthernet0/28 ! interface Vlan1 no ip address ! ip classless ip http server ! ! control-plane ! ! line con 0 line vty 5 15 ! end Switch#
interface GigabitEthernet0/1 switchport access vlan 10 switchport mode access spanning-tree portfast no cdp enable
REPEAT FOR EACH INTERFACE AN ENCODER WILL BE CONNECTED TO
To configure a group of interfaces, use the range command
interface range GigabitEthernet 0/1-12
! interface GigabitEthernet0/24 no switchport ip address 10.1.4.245 255.255.255.0 ! interface Vlan1 no ip address shutdown ! interface Vlan10 description Multicast Source ! ! ip classless ! ip route 0.0.0.0 0.0.0.0 10.1.4.254 OPTIONAL GATEWAY ADDRESS FOR VLAN 10 ! ! snmp-server community public RO snmp-server community private RW ! control-plane ! ! line con 0 line vty 0 4 password cisco line vty 5 15 password cisco ! end
After typing “end” above you will be returned to the “switch#” prompt.
The final thing to do is to enable IGMP snooping on the switch
IGMP snooping can be enabled on a switch to prevent a particular port being exposed to all multicasts on a network. For example suppose there where 100 5MBits multicast streams on the back plane of the switch and you connect a device with only a 10/100 baseT port then it will be unable to tune into a multicast since it will just see a mass of packets (broadcast storm). In order to prevent this the switch can listen into multicast joins and hosts and only allow specific multicast traffic to a port if a receiver attached requests it.
IGMP snooping is normally configured as a global command but can be assigned to specific interfaces.
To configure IGMP on for the entire switch.
