2. The FE Cache dialog box opens (Figure 22-5).

Figure 22-5. Active FE Cache Dialog Box

3. To modify your FE Cache table, do one of the following:
• Select the entry and click Flush Entry to delete one or more entries
• Click Flush Table to clear the entire table

NOTE: Flushing the table will disrupt traffic flow and clear all Forwarding Entries, and all flows must be relearned.

• Click REFRESH to refresh the contents of the table
• Click Clear to remove the statistics only (the entry in the table remains).
4. See Table 22-4 for an explanation of the FE Cache dialog box fields:
