Important Considerations - 3Com 3C17205-US - Corp SUPERSTACK 3 SWITCH 4400 24PORT Implementation Manual

Important This section contains some important considerations when using
Considerations Webcache support on the Switch 4400.
The Switch 4400 supports the SuperStack 3 Webcache 1000/3000.
The Webcache must be connected directly to the Switch 4400 —
there must be no intervening Switches or Hubs.
The Switch 4400 can only support one Webcache for a single unit or a
stack.
On the Switch 4400 the Webcache must reside on VLAN1.
The SuperStack 3 Webcache 1000/3000 can only receive untagged
packets, therefore it must be connected to an untagged port on the
Switch 4400.
The Switch 4400 only redirects HTTP requests it recognizes in VLAN1
and sends them untagged to the Webcache.
The traffic between any two pairs of IP addresses must always be
redirected through the same Webcache.
Only HTTP traffic is eligible for redirection.
The port to which the Webcache is connected cannot be a member of
an aggregated link.
IP packets with IP Options set will not be redirected.
