Chapter 8 Troubleshooting the Cisco Catalyst 6509
Catalyst 6509 Ethernet switches are used to aggregate traffic from Trunk Gateways, Network Servers,
Call Agent and the NMS server. The connections are Fast Ethernets. The key features of the Catalyst
6500 IP switch router include wirespeed Layer 3 IP, IP multicast, and forwarding across Ethernet, Fast
EtherChannel (FEC), and Gigabit EtherChannel (GEC) capability. The switch router supports virtual
LANs between switches via the Inter-Switch Link (ISL) trunk protocol and the 802.1q standard. The
switch router also provides high quality of service (QoS) capabilities, including support for four queues
per port and flow classification based on IP precedence bits.
The Catalyst 6509 is a multi-layer internal LAN switching component. It can provide high port density
Ethernet/Fast Ethernet and Gigabit switching functions. The Catalyst 6509 switch is a NEBS level-3
compliant product. It supports a wide range of interface types and densities including support for up to
384 10/100 Ethernet ports, 192 100 FX Fast Ethernet ports, and up to 130 Gigabit Ethernet ports.
The Catalyst 6509 switch also provides seamless LAN/WAN convergence in a single multi-layer
switching platform using a FlexWAN module. A wide variety of WAN interfaces, including T1/E1,
T3/E3, OC-3 ATM, and Packet over SONET (POS) functionality are supported via the port adapter
technology from Cisco 7200/7500 series platforms.
The Catalyst 6509 supports both 6 slot and 9 slot versions, providing a wide range of configuration and
price/performance options. The architecture of the Catalyst 6500 Series supports scalable switching
bandwidth up to 256 Gbps and scalable multilayer switching up to 150 Mpps.
The Ethernet switches connect into the Cisco GSR12000 or ESR10000 via Gigabit Ethernet. The routing
protocol between the CAT switches and the Call Agent is IRDP and it is OSPF in the rest of the core
network. The 6509s run HSRP so that they appear to have a single virtual IP and MAC address for the
call agent that operate best in a single LAN environment. Multiple 100Base T (Fast Ether Channel) links
between the Catalyst switches are used to maintain the throughput in case of a Gigabit Ethernet link
failure between CSR and GSR (card fail, fiber cut, and so on).
