| + | ======Managing Switching Table Sizes====== | ||
| + | =====General===== | ||
| + | * For lower-end switches, the finite memory can be adjusted to accommodate switch roles. | ||
| + | * This is done by changing the switch template. | ||
| + | * Also called: SDM, or Switch Database Management. | ||
| + | =====Template Options===== | ||
| + | * Template options include, but are not limited to. | ||
| + | * default | ||
| + | * Default bias | ||
| + | * access | ||
| + | * Access bias | ||
| + | * routing | ||
| + | * Unicast bias | ||
| + | * vlan | ||
| + | * VLAN bias | ||
| + | * dual-ipv4-and-ipv6 | ||
| + | * Supports IPv4 and IPv6 | ||
| + | * Display current template (on a 9300-24UX | ||
