The 4500 can utilize two power supplies to work in either combined or redundant
mode
Redundant Mode Combined Mode
In redundant mode, each power
supply operates at 50% capacity and
provides the same total power as a
single power supply – if one fails, the
backup reverts to providing 100%
power
In combined mode, each power
supply operates at 83% - if one fails,
then the running supply provides
100% of its power capacity

Centralized memory switch
All forwarding, queuing, security is implemented on the Supervisor
The individual line cards are considered to be ‘transparent’
No local switching on line cards
Each classic line card (WS-X41xx-WS-X45xx ) has 6 Gbps (full duplex) connections to the central forwarding engine
Each E-Series line card (WS-X46xx ) has 24 Gbps (full duplex) connection to the central forwarding engine

1. Packet enters the PHY in the line module and travels across the backplane before
reaching the Supervisor
2. Packet enters the Supervisor; IPP performs parsing of VLAN tag / header and stores the
packet into Packet Memory
3. The stripped header is used to construct a Packet Lookup Descriptor (PLD) and
forwarded to the VFE ASIC
4. PLD goes through L2 lookup. Spanning Tree state is checked. Packet MAC source and
MAC destination coupled with the receive VLAN ID are looked up in the L2 Hash Table.
L2 Lookup also determines whether the packet is destined for Router functionality
5. Input Classification is used to store input ACL and QoS rules in TCAM4
6. Packet is sent to the Forwarding Lookup CAM for L3 lookup. FLC stores L3
forwarding and unicast RPF check rules. Contains IPv4 and IPv6 FIB entries
7. Output Classification stores output ACL and QoS rules in TCAM4
8. The Packet Transmit Descriptor (PTD) is sent to the Queue Memory
9. PTD is sent back to the IPP
10. IPP transmits the packet across the backplane to the correct egress interface

1. Packet enters the PHY in the line module and travels across the backplane before

2. Packet enters the Supervisor; IPP performs parsing of VLAN tag / header and stores the
packet into Packet Memory
3. The stripped header is used to construct a Packet Lookup Descriptor (PLD) and
forwarded to the VFE ASIC . L2 lookup is performed . If the packet is a multicast packet ,
it is marked to be placed in Replication Queue.
4. PLD goes through L3 lookup. The multicast group is looked up and on a hit , RET index (
Index in the replication table ) and RPF vlan is determined.
5. The PLD are enqued into MRQ ( Multicast Replication queue ) and the dequeuing
process of MRQ created one packet per output vlan.
6. The multicast replication module ( MRM ) gets the replication information for the packet
descriptor in the MRQ from RET table ( replication table ) and replicates the packets
and sends it to the PPE with the PTD.
7. Replicated packets are recirculated through the pipeline for ACL and QOS lookup for OIL
8. Same as 7 for any additional packets
9. Packet is transmitted to the output port

When device draws more power than allocated, power to device is removed
User can configure to either log a message and restart device, or put port in errdisable state.

NSF – Non Stop Forwarding
No Route Flaps During Recovery
Following SSO recovery and activation of standby supervisor , forwarding engines continue to route the traffic based hardware FIB table
Supervisor reestablishes adjacency indicating this is NSF restart
Peer updates the newly active supervisor routing processes with its routing information
Newly active supervisor sends routing updates to the peer
RIB attaches to FIB and forwarding engine TCAMs are updated with the new FIB entries

NSF – Non Stop Forwarding
No Route Flaps During Recovery
NSF Awareness – If routing peers detect that an NSF router can still forward packets when a switchover occurs , this capability is referred to as NSF Awareness
The NSF Aware switch helps to send the routing information to NSF peer router
NSF Capable – NSF works with SSO to minimize the amount of time that an L3network is unavailable following a supervisor switchover by continuing to forward IP packets
The routing protocols recover routing information from peers and rebuild the CEFtables
