Module: CIENA-CES-MGMT-INTERFACE-MIB
OID (symbolic): CIENA-CES-MGMT-INTERFACE-MIB::cienaCesInetIcmpEchoIgnoreBroadcasts
OID (numeric): 1.3.6.1.4.1.1271.2.1.27.1.1.3.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object indicates the ICMP echo-ignore-broadcasts setting associated with this address type represented by cienaCesInetAddrType. This setting refers to whether the device will ignore ICMP Echo Request messages which are directed toward a multicast or broadcast destination address.
What is cienaCesInetIcmpEchoIgnoreBroadcasts?
This object controls whether the device ignores ICMP Echo Requests sent to a broadcast or multicast destination address (on) or responds to them (off), as the description explains. Turning it on protects the device from being drafted into a Smurf-style amplification attack, where an attacker pings a broadcast address with a spoofed source and every responding host floods that victim with replies. For example, on(1) means a broadcast ping sweep of the management subnet gets silently dropped by this box instead of eliciting a reply that could be weaponized against a spoofed target.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1271.2.1.27.1.1.3.1.5 snmpwalk -v2c -c public <target> CIENA-CES-MGMT-INTERFACE-MIB::cienaCesInetIcmpEchoIgnoreBroadcasts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1271.2.1.27.1.1.3.1.5.1 snmpget -v2c -c public <target> CIENA-CES-MGMT-INTERFACE-MIB::cienaCesInetIcmpEchoIgnoreBroadcasts.1
