38. Default Gateway Operation The default gateway is required when a router is needed for tasks such as reaching off subnet destinations or forward ing traffic across multiple VLANs The gateway value is the IP address of the next hop gateway node for the switch which is used if the requested destina tion address is not on a local subnet VLAN If the switch does not have a manually configured default gateway and DHCP Bootp is configured on the primary VLAN then the default gateway value provided by the DHCP or Bootp server will be used If the switch has a manually configured default gateway then the switch uses his gateway even if a different gateway is received via DHCP or Bootp on the primary VLAN This is also true for manually configured TimeP SNTP and Time To Live TTL In the default configuration VLAN 1 is the Primary VLAN Refer to the information on Primary VLANs in the Advanced Traffic Management Guide for your switch Packet Time To Live TTL This parameter specifies the maximum num ber of routers hops through which a packet can pass before being discarded Each router decreases a packet s TTL by 1 before forwarding the packet If decreasing the TTL causes the TTL to be 0 the router drops the packet instead of forwarding it In most cases the default setting 64 is adequate Just Want a Quick Start with IP Addressing If you just want to give the switch an IP address so that it can communicate on your network or if
