-
AH
 —
 Authentication Header
 (AH). Provides source host authentication 
and data integrity.
-
EIGRP
 —
 Enhanced Interior Gateway Routing Protocol
 (EIGRP). Provides 
fast convergence, support for variable-length subnet mask, and 
supports multiple network layer protocols. 
-
OSPF
 — The 
Open Shortest Path First 
(OSPF) protocol is a link-state, 
hierarchical Interior Gateway Protocol (IGP) for network routing Layer 
Two (2) Tunneling Protocol, an extension to the PPP protocol that 
enables ISPs to operate Virtual Private Networks (VPNs).
-
IPIP
 —
 IP over IP
 (IPIP). Encapsulates IP packets to create tunnels 
between two routers. This ensure that IPIP tunnel appears as a single 
interface, rather than several separate interfaces. IPIP enables tunnel 
intranets occur the internet, and provides an alternative to source 
routing. 
-
PIM
 — Matches the packet to 
Protocol Independent Multicast
 (PIM).
-
L2TP 
— Matches the packet to 
Layer 2 Internet Protocol 
(L2IP).
-
ISIS
 —
 Intermediate System - Intermediate System
 (ISIS). Distributes IP 
routing information throughout a single Autonomous System in IP 
networks.
-
ANY
 — Matches the protocol to any protocol.
• Source Port — Defines the TCP/UDP source port to which the ACE is matched. 
This field is active only if 800/6-TCP or 800/17-UDP are selected in the Select 
from List drop-down list. The possible field range is 0 - 65535.
• Destination Port — Defines the TCP/UDP destination port. This field is active 
only if 800/6-TCP or 800/17-UDP are selected in the Select from List drop-
down list. The possible field range is 0 - 65535.
• Flag Set — Sets the indicated TCP EtherChannel that can be triggered.
• ICMP Type — Filters packets by ICMP message type. The field values is 0-255.
• ICMP Code — Indicates and ICMP message code for filtering ICMP packets. 
ICMP packets that are filtered by ICMP message type can also be filtered by 
the ICMP message code.
• IGMP Type — Filters packets by IGMP message or message types.
• Source
