To filter SNA traffic, use a Service Access Point (SAP) access list in the 200-299 range.
A SAP is protocol identifier at the data-link-layer. It's used by IEEE protocols. Technically, it's part of the IEEE 802.2 Logical Link Control (LLC) header. It identifies what the next layer up is. Here's a quick list. Notice SNA uses a few! IPv4 0x06 (usually uses EtherType, but could use 802.2) IPv6 0x06 (usually uses EtherType, but could use 802.2) IP ARP 0xAA (uses SNAP if 802.2 is used) SNAP 0xAA ATalk Ph 2 0xAA (uses SNAP) ATalk ARP 0xAA (uses SNAP) NetWare 0xEO NetBEUI 0xF0 SNA 0x04, 0x05, 0x08, 0x0C IS-IS 0xFE BPDU 0x42 CDP 0xAA Priscilla Cisco Nuts wrote: > > Hello,If I were to permit only SNA traffic between 2 routers > under DLSW+, > what values would I use under the access-list?Ex. #access-list > 299 permit > 0x...... 0x.....
