A simulator, as the name suggests, simulates network devices and its environment, so protocols in Packet Tracer are coded to work and behave in the same way as they would on real hardware. The following table shows the protocols supported by Packet Tracer:
|
Technology |
Protocols |
|---|---|
|
LAN |
Ethernet (including CSMA/CD*), 802.11 a/b/g/n wireless*, and PPPOE |
|
Switching |
VLANs, 802.1q, trunking, VTP, DTP, STP*, RSTP*, multilayer switching*, EtherChannel, LACP, and PAgP |
|
TCP/IP |
HTTP, HTTPS, DHCP, DHCPv6, Telnet, SSH, TFTP, DNS, TCP*, UDP, IPv4*, IPv6*, ICMP, ICMPv6, ARP, IPv6 ND, FTP, SMTP, POP3, and VOIP(H.323) |
|
Routing |
Static, default, RIPv1, RIPv2, EIGRP, single area OSPF, multiarea OSPF, BGP, inter-VLAN routing, and redistribution |
|
WAN |
HDLC, SLARP, PPP*, and Frame Relay* |
|
Security |
IPsec, GRE, ISAKMP, NTP, AAA, RADIUS, TACACS, SNMP, SSH, Syslog, CBAC, Zone-Based Policy Firewall, and IPS |
|
QoS |
Layer 2 QoS, Layer 3 DiffServ QoS, FIFO Hardware queues, Priority Queuing, Custom Queuing, Weighted Fair Queuing, MQC, and NBAR* |
|
Miscellaneous |
ACLs (standard, extended, and named), CDP, NAT (static, dynamic, inside/outside, and overload), and NATv6 |
* These protocols have substantial modelling limitations, so not all commands under these protocols work.
