enable icmp parameter-problem {vlan <name>} Enables the generation of an ICMP
parameter-problem message (type 12) when
the switch cannot properly process the IP
header or IP option information. The default
setting is enabled. If a VLAN is not specified,
the command applies to all IP interfaces.
enable icmp port-unreachables {vlan <name>} Enables the generation of ICMP port
unreachable messages (type 3, code 3) when
a TPC or UDP request is made to the switch,
and no application is waiting for the request, or
access policy denies the request. The default
setting is enabled. If a VLAN is not specified,
the command applies to all IP interfaces.
enable icmp redirects {vlan <name>} Enables the generation of an ICMP redirect
message (type 5) when a packet must be
forwarded out on the ingress port. The default
setting is enabled. If a VLAN is not specified,
the command applies to all IP interfaces.
enable icmp time-exceeded {vlan <name>} Enables the generation of an ICMP time
exceeded message (type 11) when the TTL
field expires during forwarding. IP multicast

enable icmp unreachables {vlan <name>} Enables the generation of ICMP network
unreachable messages (type 3, code 0), and
host unreachable messages (type 3, code 1)
when a packet cannot be forwarded to the
destination because of unreachable route or
host. ICMP packet processing on one or all
VLANs. The default setting is enabled. If a
VLAN is not specified, the command applies to
all IP interfaces.
enable icmp useredirects Enables the modification of route table
information when an ICMP redirect message is
received. This option applies to the switch
when it is not configured for routing. The
default setting is disabled.
enable ip-option loose-source-route Enables the loose source route IP option.
enable ip-option record-route Enables the record route IP option.
enable ip-option record-timestamp Enables the record timestamp IP option.
enable ip-option strict-source-route Enables the strict source route IP option.
enable ip-option use-router-alert Enables the switch to generate the router alert
