5 Network Loops
Network loops may be indicated by service degradations, connectivity problems on a link(s), etc. If the user
suspects the presence of a network loop, they should attempt to find the loop and correct it. Some things that
the user should look at are recent port and interface provisioning, recent EPSR provisioning, recent STP provi-
sioning, and recent wiring and connections made within their network or connections external to their net-
work.
