Management of QoS Policies

Flexible Layer 3 Switching Line Card Architecture

Each line card can be conﬁgured for either 16,000 or 64,000

address entries per port. Each address entry could be one of the

following types: Layer 2 Media Access Control (MAC) address,

an IP address, an IP network number, an IPX network number, or

an IPX station address. The 16,000 address entries option is

suitable for most enterprises, and the 64,000 address entries

option is suitable for large enterprises and ISPs.

The line cards are available in Fast and Gigabit Ethernet,

with ATM and Packet over SONET uplinks to be released in the

future. Gigabit Ethernet line cards will use the Gigabit Interface

Controller (GBIC) interface for ﬂexible per-port conﬁguration of

the interface types. GBICs are available in the short wavelength

multimode ﬁber, long wavelength multimode ﬁber, and

single-mode ﬁber interface types. Fast Ethernet interfaces are

available in the 10/100 unshielded twisted-pair (UTP) and

multimode ﬁber media types.

The Catalyst 8500 switch family consists of the

Catalyst 8510 and 8540, 5- and 13-slot modular chassis-based

implementations of the Catalyst 8500 technology.

Catalyst 8510 System Components

The Catalyst 8510 is a modular ﬁve-slot chassis switch with dual,

redundant, load-sharing power supplies. One of the slots (center

slot) is dedicated to the SRP or MSRP and the remaining four

slots are available for line cards. A detailed description of the

system components follows:

• Five-slot chassis with passive backplane and fan tray

• Dual redundant, load-sharing power supplies with AC or DC

(–48V) options

• SRP/MSRP running Cisco IOS software with a choice of

software; SRP/MSRP consists of the nonblocking, low-latency,

10-Gbps shared-memory switching fabric, dynamic packet

memory, and a MIPS R4600 CPU running the Cisco IOS

software

• Up to four line cards for the Catalyst 8510; Tables 2 and 3 give

the full set of line card options
