Because the maximum size of Ethernet II frame is already 1518 bytes. If the MSS option is ommitted by one or both ends of the connection, the value of 536 bytes is used.The default value of IP datagram is 576 bytes. If we mines the standard IP header and the TCP header (40 bytes), it gives us the 536 bytes.

The Cisco Adaptive Security Appliance supports both static routes and dynamic routing protocols such as OSPF, RIP, and EIGRP. For this integration you need to configure static routes that define the next hop address for IP traffic routed to the inside interface and for traffic routed to the outside interface of the Cisco Adaptive Security Appliance.

In most cases, the optimum value for the max-segment-size argument of the ip tcp adjust-mss command is 1452 bytes. This value plus the 20-byte IP header, the 20-byte TCP header, and the 8-byte PPPoE header add up to a 1500-byte packet that matches Se hela listan på cisco.com Cisco routers provide a basic method of viewing IP traffic switched through the router called packet debugging. Packet debugging enables a user to determine whether traffic is travelling along an expected path in the network or whether there are errors in a particular TCP stream.
