Transparent Web Cache Redirect
The web cache redirect feature on the SSR works in conjunction with a cache server to store commonly accessed
HTTP objects locally on the cache server. This results in substantial cost savings by saving on WAN access costs
and increasing the response time tremendously. This feature offers redundancy and load sharing capabilities for
building high availability cache server farms. Web caching is transparent to the user.
The web-cache set maximum connections command is currently not supported.
Per Protocol VLANs
In addition to IP and IPX, the protocols supported by SSR for protocol based VLANs are IPv6, DEC, SNA and
AppleTalk. Note: Only IP and IPX can be routed by the SSR.
DHCP (Dynamic Host Configuration Protocol) Server
DHCP Server on the SSR provides dynamic address assignment and configuration to DHCP capable end-users.
The SSR DHCP Server can provide a dynamic IP address from a pre-allocated pool of IP addresses or a static IP
address. The SSR DHCP server is not designed to work as primary DHCP server in an enterprise environment.
Please refer to "Known Restrictions and Limitations" for the SSR DHCP Server limitations.
Telnet Client
The SSR 's telnet client allows users to telnet from a SSR system CLI into other SSRs or systems to perform
remote configuration. Only one active telnet session from the SSR is allowed at a time.
ICMP Router Discovery Messages
ICMP Router Discovery Messages enable hosts to discover the existence of neighboring routers. A periodic
multicast advertisement is sent announcing the IP address(es) of that interface. Hosts discover the addresses of
their neighboring routers simply by listening to the advertisement.
Established Bit ACL
Established Bit ACL is an enhancement to the existing ACL feature. It allows network administrator to either
permit or deny TCP connections being "established". Established Bit ACL can only be enabled from the TCP ACL
configuration. The network administrator then applies this ACL to the IP interface.
